In the first numbers ound I saw Rachel's solution, but also had these solutions: 2 + 1 = 3 75 / 3 = 25 25 x 8 = 200 4 x 2 = 8 200 + 8 = 208 4 - 1 = 3 75 / 3 = 25 2 / 2 = 1 25 + 1 = 26 26 x 8 = 208 4 + 1 = 5 75 / 5 = 15 15 - 2 = 13 13 x 8 x 2 = 208 In the second numbers round, the contestants both made it really much harder than necessary. It was a two-step problem: 25 x 9 = 225 225 - 8 = 217 However, I did see Caroline's solution and I thought I'd be offering it as one of the alternatives, because I really did think they'd spot the obvious way. I also had this from factoring: 100 / 25 = 4 9 x 4 = 36 8 - 3 = 5 36 - 5 = 31 31 x 7 = 217 And another way was: 7 - 3 = 4 25 x 4 = 100 100 + 100 + 9 + 8 = 217 In the third numbers round, I saw Rachel's method and I'm sure the other way she had in mind was: 25 x 10 = 250 10 - 2 = 8 250 - 8 = 242 242 x 4 = 968 Or she might have had it this way: 25 - 1 = 24 24 x 10 x 4 = 960 10 - 2 = 8 960 + 8 = 968 In the final numbers round, Rachel spiked my guns because I saw it the way she did it, except that for fun I multiplied all the way across to get it up to 18,000 before dividing by 25. However, I can have some more modest fun: 100 - 25 = 75 75 + 5 = 80 80 x 9 = 720 720 - 3 = 717 5 x 4 = 20 100 - 20 = 80 80 x 9 = 720 720 - 3 = 717 100 x 9 = 900 900 x 4 = 3600 3600 / 5 = 720 720 - 3 = 717
I: Got Rachel's solution within the time. Usually don't get those which have a bit of the tricky way to get there... :) II: That one got me. III: Got closer than the first player: 10X4=40 40-1=39 39X25=975 975-10=965 965+2 gets one away. And once again I get humbled because they want us to factor it... IV: Ouch. Surprised neither player got the easy 716: 4+3=7 7X100=700 700+25=725 Subtract the 9 for one away.
Third one (968) was tricky My first thing is to get the target using only prime factors. Here, 968/8=121, so you have 8*11*11. Could you get the 88? You can. Please see my post for that.
For 217 I got 25 × 9 = 225 OR (100 - 25) × 3 = 225 225 - 8 = 217 For 968 I got 25 - 1 = 24 24 × 10 = 240 240 + 2 = 242 242 × 4 = 968 I got this by spotting 25 × 4 × 10 = 1000, and then I could just add or take something at each stage to get 968
He wrote it down, so if he wrote down 4+3 but mispronounced it’s fine as his working is there. Someone probably checked it and it didn’t make the final TV edit. It wouldn’t have been allowed if he declared it as not written down though, the timings are also very strict on a not written down declaration to avoid people trying to just make it up on the spot
25*10=250 250- (10-2)=242 242*4= 968 BUT on the Celebrity version when she was giving out tips on the first numbers round she mentioned there is a way to spot factors of 11: take a 3 digit number ABC add A to C and if it equals B it's divisible by 11 (11* AC = ABC), but there are some that are hidden like 968. 11*11=121 A+C=B 11*22=242 2+2=4 33... 363 44... 484 54... 594... 5+4=9 55... 605... 5+5=10 the 5 from A just got hidden by the 1 of 10 from the B. 66... 726 11*77=847... 7+7=14 11*88=968... 8+8=16 99... 1089... 9+9=18 The factors of 9 are fun to play with but I can see why Rachel likes 11, still working on figuring out her love of the number 7.
This time, all of them were easy if only you stick to the method of using what you have. 208 - You have a 2, which gets you to 104. Can you make 104? Yes. Done. 217 - You have a 7, which gets you to 31. Can you make 31? Yes (and much easier than she did, 25+9-3). 968 - You have a 25, which gets you to 40. Can you make 40? Yes, and the two factors allow you get to the 968: 25x10 is 250, x4 would get you 32 away, so you need an 8 to substract, and you have an 8 from 10-2. 717 - You have a 9, which gets you to 80. Can you make 80? Yes. 100 +5 - 25. And -3 for the win. It does not always work, obviously, but usually it doesn't take very long, so if it is a dead end, you still have some time left. _
It's much easier to follow if you do it logically one step at a time rather than making one big line. 100+5-25=80 80×9=720 720-2=717 The way you've written it is just much harder to follow?
217:
25 * 9 = 225
225 - 8 = 217
9 - 7 = 2
100 * 2 = 200
200 + 25 - 8 = 217
25 + 3 = 28
28 * 8 = 224
224 - 7 = 217
217 took me all of two seconds off the bat. 25 x 9 - 8 = 217.
How did you get the 25

7:28 had 718=100*5+25*9-4-3
Same way for 208 for me
lol on the first one he was 1 away then did -4 to be 3 away
I had to pause it to check I hadn’t lost my mind. I don’t know how Rachel kept a straight face.
In the first numbers ound I saw Rachel's solution, but also had these solutions:
2 + 1 = 3
75 / 3 = 25
25 x 8 = 200
4 x 2 = 8
200 + 8 = 208
4 - 1 = 3
75 / 3 = 25
2 / 2 = 1
25 + 1 = 26
26 x 8 = 208
4 + 1 = 5
75 / 5 = 15
15 - 2 = 13
13 x 8 x 2 = 208
In the second numbers round, the contestants both made it really much harder than necessary. It was a two-step problem:
25 x 9 = 225
225 - 8 = 217
However, I did see Caroline's solution and I thought I'd be offering it as one of the alternatives, because I really did think they'd spot the obvious way. I also had this from factoring:
100 / 25 = 4
9 x 4 = 36
8 - 3 = 5
36 - 5 = 31
31 x 7 = 217
And another way was:
7 - 3 = 4
25 x 4 = 100
100 + 100 + 9 + 8 = 217
In the third numbers round, I saw Rachel's method and I'm sure the other way she had in mind was:
25 x 10 = 250
10 - 2 = 8
250 - 8 = 242
242 x 4 = 968
Or she might have had it this way:
25 - 1 = 24
24 x 10 x 4 = 960
10 - 2 = 8
960 + 8 = 968
In the final numbers round, Rachel spiked my guns because I saw it the way she did it, except that for fun I multiplied all the way across to get it up to 18,000 before dividing by 25. However, I can have some more modest fun:
100 - 25 = 75
75 + 5 = 80
80 x 9 = 720
720 - 3 = 717
5 x 4 = 20
100 - 20 = 80
80 x 9 = 720
720 - 3 = 717
100 x 9 = 900
900 x 4 = 3600
3600 / 5 = 720
720 - 3 = 717
The first one I dunno why the guy included the 4, if he'd just taken off the 16 he'd have been one away!
For the 717, I did what the contestants did but took away the 9, as Rachel said. Surely 1 away is better than 3?
If you said
100-25=75
75+5=80
80*9=720
And 720-3 gives you the 717.
Sometimes I see it quick, or not at all 🙈
@simonrodgers8902 Humans do funny things when under pressure :)
Got the Conundrum.
I: Got Rachel's solution within the time. Usually don't get those which have a bit of the tricky way to get there... :)
II: That one got me.
III: Got closer than the first player:
10X4=40
40-1=39
39X25=975
975-10=965
965+2 gets one away.
And once again I get humbled because they want us to factor it...
IV: Ouch. Surprised neither player got the easy 716:
4+3=7
7X100=700
700+25=725
Subtract the 9 for one away.
75 : (2 + 1) = 25 x 8 = 200 + (2 x 4) = 208
100 - 25 = 75 x 3 = 225 - 8 = 217
just didn't see the third
100 - (5 x 4) = 80 x 9 = 720 - 3 = 717
Got 217 this way.
Third one (968) was tricky
My first thing is to get the target using only prime factors. Here, 968/8=121, so you have 8*11*11. Could you get the 88? You can. Please see my post for that.
968:
(25 - 1) * (10 * 4) = 24 * 40 = 960
960 + 10 - 2 = 968
I did (25x10)-10+2=242, 242x4=968, which is actually the simplest way of doing it
First time in living history that I’ve ever got the conundrum.
1. 75/(1+2)=25x2x4+8=208
2. (25+9-3)x7=217 or (25+3)x8-7=217
3. (25x10-10+2)x4=968 or (4x25-2-10)x(1+10)=968
4. (25-5)x4x9-3=717
717=9×(100-25+5)-3
First round 208
4*8=32, 32+75=107, 107-2-1=104, 104*2=208
Second round 217
9×25=225, 225-8=217
Third round 968
4×10=40, 25-1=24, 40×24=960, 10-2=8, 960+8=968
Fourth round 717 - one away in 30 seconds
3+4=7, 7×100=700, 25-9=16, 700+16=716
For 217 I got
25 × 9 = 225 OR (100 - 25) × 3 = 225
225 - 8 = 217
For 968 I got
25 - 1 = 24
24 × 10 = 240
240 + 2 = 242
242 × 4 = 968
I got this by spotting 25 × 4 × 10 = 1000, and then I could just add or take something at each stage to get 968
217 was the easiest, (25x9)-8.
I got that. I don't know why the contestants didn't do it like that.
Round 1
(75 / (2 + 1)) x 8 + (2 x 4)
Round 2
(25 + 3) x 8 - 7
Round 3
(25 x 10 - 10 + 2) x 4
Round 4
(100 - 25 + 5) x 9 - 3
208=2x(75+((8-1)x4))+2
217=100x(9-7)+(25-8)
968= (25-1)x(4x10)+(10-2)
Got 968 this way as well.
I got 717 in a similar way, but I did 100 - (4 * 5) to get the 80.
25x9 - 8 = 217. I prefer the contestant’s solution but couldn’t be bothered to look at factors when it was so easy the basic way.
7:00 surprised that this was overlooked, he clearly muddled up his solution and Rachel wrote down the wrong calculation. No VAR check?
He wrote it down, so if he wrote down 4+3 but mispronounced it’s fine as his working is there. Someone probably checked it and it didn’t make the final TV edit. It wouldn’t have been allowed if he declared it as not written down though, the timings are also very strict on a not written down declaration to avoid people trying to just make it up on the spot
Same of Rachel but also 25*10=250+2-10=242*4=968
717:
100 + 5 - 25 = 80
80 * 9 = 720
720 - 3 = 717
5 * 4 = 20
100 - 20 = 80
80 * 9 = 720
720 - 3 = 717
25 - 5 = 20
20 * 9 * 4 = 720
720 - 3 = 717
You could say
25 × 10 = 250 -

8 times 9 is 72.
So I’m only one away anyway. Ive got dead ball delivery.
3 times 7 is 21
For 968 I did 25*4=100*10=1000 then 10*3=30 and take that off to make 970
Rachel over-complicated the 717 round.
25-5=20
20*4=80
80*9=720
720-3=717
4+1 = 5 75÷5 = 15-2 = 13X8 = 104X2 = 208
4-1 = 3 75÷3 = 25 2÷2 = 1+25 = 26X8 = 208
9-3 = 6+25 = 31X7 = 217
7X3 = 21-8 = 13X9 = 117+100 = 217
25X4 = 100-10-2 = 88 10+1 = 11X88 = 968
10-8 = 2 25X10 = 250-8 = 242X4 = 968
100-25+5 = 80X9 = 720-3 = 717
25+4 = 29X9 = 261 100X5 = 500-261 = 239X3 = 717
2nd one 9X25 = 225
225 -8= 217
4th one 100/25 = 4
9X5=45
4x4= 16
16X45=720
720- 3=717
25 * 9 = 225
225 - 8 = 217
I am shocked that neither of them spotted that.
I replied realising I used one of the two twice.
Yes, me too - saw that straight away
all avenues work
You can take the 9, you can take the 7, you can also take the 8x(25+3)
(25*9)-8 = 217
25 times 4 is 100 times 10 is 1,000.
100 + 25 = 125
8 + 3 = 11
11 x 9 = 99
99 - 7 = 92
(125 + 92 = 217)
whyd he do 205 when 209 was right there
and they both did 720 when they couldve had 716…. insane
The school teacher look for Rachel today.
Perhaps a college professor??
First one was again very easy if you stick to the method of using what you have. You have a 2, which brings you to 104. Can you make 104? Yes. Done.
208:
8 * 4 = 32
75 + 32 - 2 - 1 = 104
104 * 2 = 208
2 + 1 = 3
75 / 3 = 25
25 * 4 * 2 = 200
200 + 8 = 208
4 - 1 = 3
75 / 3 = 25
2 / 2 = 1
25 + 1 = 26
26 * 8 = 208
25-1 =24
X 4 = 96
X 10 = 960
Other 10 - 2 = 8
960 + 8.
7-3=4x25=100+100+9+8=217
4(25x10 + 2 - 10) = 968.
For 968 I saw an easy way to take 40 off 1000:
10*4=40
40*(25-1)=960
960+10-2=968
25*10=250
250- (10-2)=242
242*4= 968
BUT on the Celebrity version when she was giving out tips on the first numbers round she mentioned there is a way to spot factors of 11:
take a 3 digit number ABC add A to C and if it equals B it's divisible by 11 (11* AC = ABC), but there are some that are hidden like 968.
11*11=121 A+C=B
11*22=242 2+2=4
33... 363
44... 484
54... 594... 5+4=9
55... 605... 5+5=10 the 5 from A just got hidden by the 1 of 10 from the B.
66... 726
11*77=847... 7+7=14
11*88=968... 8+8=16
99... 1089... 9+9=18
The factors of 9 are fun to play with but I can see why Rachel likes 11, still working on figuring out her love of the number 7.
25 x 10 = 250 - 10 + 2 = 242 x 4 = 968
217=7×(25+9-3)
217=8×(25+3)-7
125+72=197.
968:
25 - 1 = 24
24 * 10 = 240
240 + 2 = 242
242 * 4 = 968
25 * 10 = 250
250 + 2 - 10 = 242
242 * 4 = 968
10 + 1 = 11
25 * 4 = 100
100 - 10 - 2 = 88
88 * 11 = 968
968=(10+1)×(4×25-10-2)
968 = (25 - 1) * 4 * 10 + 10 - 2
{[(25 - 1) × 10] + 2} × 4 = (240 + 2) × 4 = 968.
100+25=125.
Then you’ve only got 20 left.
This time, all of them were easy if only you stick to the method of using what you have.
208 - You have a 2, which gets you to 104. Can you make 104? Yes. Done.
217 - You have a 7, which gets you to 31. Can you make 31? Yes (and much easier than she did, 25+9-3).
968 - You have a 25, which gets you to 40. Can you make 40? Yes, and the two factors allow you get to the 968: 25x10 is 250, x4 would get you 32 away, so you need an 8 to substract, and you have an 8 from 10-2.
717 - You have a 9, which gets you to 80. Can you make 80? Yes. 100 +5 - 25. And -3 for the win.
It does not always work, obviously, but usually it doesn't take very long, so if it is a dead end, you still have some time left.

"217 whatever"?
Something to do with some banter we didn't see. Rachel said "That put Colin Murray in his place" as she was picking the numbers.
