I thought of crustier for the second teatime teaser, and I checked it to be sure it's a word (it is.) That's a bad teaser if it has a perfectly acceptable anagram, good thing it didn't count for anything.
1. OUT OF THE TIME: 3x5x6x9-8-9=793 2. LNAFP: (8x9+2x6)x10=840 or (100+9-6+2)x8=840 3. 75/3x25-50/10=620 or (75-3)x10-100=620 or (100+75+50-10)x3-25=620 4. LNAFP: (6+7+10)x(1+7)=192 5. DARTBOARD
@escapedlunatic27 I teach in the mountains of the Philippines...I give my elementary students 2 minutes to find a solution & sometimes they come up with multiple solutions!!
(9 × 9 + 3 × 6) × 8 = -1 (missed it by a hair) 100 × 8 + 10 × (6 - 2) = 0 (there we go, that's more like it) (100 + 75 + 25 + 50 ÷ 10) × 3 = -5 (closest I can get with this) [100 - (10 - 6)] × (7 - 5) = 0 (and a nice one to close things out)
IS IT?, IT'S A BULLSEYE!!! 7:17

I've had that happen before. Sometimes it even fits the clue.
Using all the numbers in order, 192 = 100 + 6*7 + 10*1*5
or 100-6+7(10-1+5)
1. OUT OF THE TIME: 3x5x6x9-8-9=793
2. LNAFP: (8x9+2x6)x10=840 or (100+9-6+2)x8=840
3. 75/3x25-50/10=620 or (75-3)x10-100=620 or (100+75+50-10)x3-25=620
4. LNAFP: (6+7+10)x(1+7)=192

620=25×(100-75)-50/10
9+8 = 17 3X5 = 30 9X3 = 27X30 = 810-17 = 793
9X8 = 72 100-72 = 28X10 = 280X6 = 1,680÷2 = 840
8X2 = 16 100-16 = 84X10 = 840
100+50 = 150÷10 = 15 75X25 = 1,875-15 = 1,860÷3 = 620
75-3 = 72X10 = 720-100 = 620
100÷5 = 20 10-6 = 4+20 = 24 7+1 = 8X24 = 192
10+6 = 16 7+5 = 12X16 = 192
I did (6*7)+(10*5)+100 = 192. Somehow I saw that before any of the ways which just involve multiplying to get there!

For 192 I did 10-6=4, 100-4=96, and then 96x(7-5)=192
For 840:
100 - (8 × 2) = 84
84 × 10 = *_840_*
For 192:
100 - (10 - 6) = 96
96 × (7 - 5) = *_192_*
192 = 100 + 5*10 + 6*7
620:
75 - 3 =72
72 * 10 =720
720 - 100 =620
100 * 3 =300
300 + 10=310
310 * 50 / 25 =620
100 * 3 / 25 =12
50 + 12 =62
62 * 10 =620
75 * 25 / 3 =625
50 / 10 =5
625 - 5 =620
100 × 9 = 900 6 × 10 = 60 900 - 60 = 840
100 ÷ 25 = 4 × 3 = 12 + 50 = 62 × 10 = 620
100 - 10 + 6 = 96 7 - 5 = 2 96 × 2 = 192

Also crustier. 👍
192:
100 * 10 / 5 =200
200 - 7 - 1 =192
100 - 1 =99
99 * 10 / 5 =198
198 - 6 =192
100 - 7 =93
93 * 10 / 5 =186
186 + 6 =192
10 * 5 =50
7 * 6 =42
100 + 50 + 42 =192
10 + 6 =16
7 + 5 =12
16 * 12 =192
For 840, it took me a while, but I found a simpler way
9*100=900 - (6*10)
7:18 *IT’S A BULLSEYE!*
620 (out of time)
25x 75 = 1875
(100 + 50) / 10. = 15
(1875 - 15)/3 = 620
(9 × 9 + 3 × 6) × 8 = -1 (missed it by a hair)
100 × 8 + 10 × (6 - 2) = 0 (there we go, that's more like it)
(100 + 75 + 25 + 50 ÷ 10) × 3 = -5 (closest I can get with this)
[100 - (10 - 6)] × (7 - 5) = 0 (and a nice one to close things out)
192
(10+6)×(7+5)
793=3×5×6×9-9-8
192=100+(5-1)×(10+7+6)
620 =
((100 - 75) * 25) - (50 / 10)
840: (8×100)×(6-2×10)
=32000
840=10×(8×9+2×6)
840=8×100+(6-2)×10
840=9×100-6×10
840=(9-2)×(100+(8-6)×10)
840=10×(100-2×8)
840=(100+8*10/2)*6
