The Magic Number➖➕by Howard Thurston

[@MarcosNaceli]

Hey people, note this:
* Any 3 *all different* numbers. Including 0.
* After the first substraction: ignore the negative (-) and consider any two digit number as a three digit number filling with a zero.
Example 1: 506-605=-99 change -99 to 099. Its reverse is 990. Finally: 099+990=1089.
Example 2: 012-210=-198. change it to 198. Finally: 198+891=1089.
Have fun! :)

It's really a stretch to make it work when the difference is 99. For example 231-132=99. You'd need to see the 99 as 099, then reverse to 990. Adding back 990 to 99 does get you 1089.

[@timlonsdale]

Represent the number as: 1*X + 10*Y + 100*Z.
The inverse would be: 1*Z + 10*Y + 100*X.
Subtract the inverse and get: 99*Z - 99*X.
Also can be written as: 99*(Z-X).
Lets replace (Z-X) with N: 99*N.
Lets rewrite as: 100*N - N.
Lets rewrite as 100*(N-1) + 100 - N.
Lets rewrite as 100*(N-1) + 90 + (10-N).
Thus the inverse is: 100*(10-N) + 90 + (N-1).
Add these together and we get: 99*N + 1000 - 100*N + 90 + N - 1.
Squish together and get: 1000 + 90 - 1 = 1089

If abc is the 3 different digit number we can write it algebraically as 100a+10b+c
Then the reverse digit number will be 100c+10b+a
Now subtract the reverse digit number from original one
(100a+10b+c)-(100c+10b+a)
The new number will be
(100-1)a+(10-10)b+(1-100)c
Or
99a-99c
Or *99(a-c)* ..... (1)
Since a and c are single digit numbers i.e
a, b belongs [0,1,2,3,4,5,6,7,8,9]
So (a-c) will also be a single digit number.
[But a≠0 because abc is a 3 digit number]
Henc (a-c) belongs to [1,2,3,4,5,6,7,8,9]
_We excluded 0 because
a-c=0 if and only if a=c
And we know that a,b and c are three different digits. a≠c
Now lets substitute the other possible values of (a-c) one by one
For *a-c=1*
(1)=> 99×1=99
Now add reverse
99+99=198
Add reverse digit number again
198+891=1089
For *a-c=2*
(1)=> 99×2=198
Now add reversed digits
198+891=1089
For *a-c=3*
(1)=> 99×3=297
Now add reversed digits
297+792=1089
For *a-c=4*
(1)=> 99×4=396
Now add reversed digits
396+693=1089
For *a-c=5*
(1)=> 99×5=495
Now add reversed digits
495+594=1089
For *a-c=6*
(1)=> 99×6=594
Now add reversed digits
594+495=1089
For *a-c=7*
(1)=> 99×7=693
Now add reversed digits
693+396=1089
For *a-c=8*
(1)=> 99×8=792
Now add reversed digits
792+297=1089
For *a-c=9*
(1)=> 99×9=891
Now add reversed digits
891+198=1089
Similarly for negative values of (a-c)
Ignore the negative we will conclude with the same answers.
I have tried to verify it by putting all possible values. I will be more than grateful if you share your kind opinion or correction.

[@smartanon_5299]

It was sweet and concise until the last part, thanks a lot for the explanation. (but...)
(let d = a-c)
99(d)+(inverted_99(d)_) = 99(11) = 1089
I am having a hard time proving that last part but it has to do with prime numbers added to 11.
For 2, 2+9 and 9+2, for 3, 3+8 and 8+3, 5 goes with 6, 7 goes with 4. 1 is not a prime number and doesn't go with anything hence i am having a hard time finding the rule that would render the last part of your reasoning slick and concise like the first part was...
1089 is 33 squared, (11)(99), (11)(11)(3)(3).

Mathematical explanation:
Let's say that the hundreds digit is greater than the units digit (if its the other way you will need to negate the result which is basically like negating the first operation and -(x-y)=y-x so we can continue as if it was this way to begin with) and let's call the hundreds digit "a" and the units digit "b" so a>b.
I will also represent the numbers with their digits divided by commas so I would be able to represent digits with algebraic expressions (132=1,3,2)
Step #1: subtract the reverse:
Let's separate the subtraction into steps:
A. Subtract the middle digit: the middle digit will be subtracted by itself so it does not matter. We are left with a,0,b - b,0,a
B: Subtract the hundreds digit: as a>b we know that the result will only affect the hundreds digit. Now we are left with (a-b),0,b - a
C: Subtract the units digit: as b

Here's why it happens:
1. **Three-Digit Number**: Consider any three-digit number where the first and last digits differ by at least two. Let's call it ABC, where A, B, and C are its digits.
2. **Reversing and Subtracting**: When you reverse this number, you get CBA. Subtracting CBA from ABC (assuming A is greater than C) gives a new number. This subtraction aligns with the form (100A + 10B + C) - (100C + 10B + A) = 99A - 99C.
3. **Result of Subtraction**: Simplifying 99A - 99C, you get 99(A - C). Since A and C are at least two digits apart, the minimum value for (A - C) is 2 (e.g., if A is 3 and C is 1), and the maximum is 9 (e.g., if A is 9 and C is 0). This results in a number that is two digits long, and its first digit is always 9.
4. **Intermediate Number Characteristics**: The intermediate number (after subtraction but before adding the reverse) is always of the form 9X9, where X is a digit. This is because the hundreds and units place will always be 9 due to the subtraction process described above.
5. **Reversing the Intermediate Number**: When you reverse this number, it becomes 9X9 again, as reversing doesn't change the position of the digits due to its symmetry.
6. **Final Sum**: Adding the intermediate number and its reverse, both being 9X9, will always lead to 1089. This is because 900 + 90 + 9 equals 999, and adding it to another 999 (since the reverse is the same) results in 1089.
In summary, the specific properties of base-10 subtraction and the constraints placed on the original number (three digits, first and last digits differ by at least two) ensure that this trick works, leading to the consistent result of 1089.

[@ayamrudin7985]

The claim should be that the difference of any number (greater than 9 and not equal to its mirrored version) and its mirrored version, is always divisible by 9. Essentially, it all comes down to this:
If a>0; x, y ≥ 0; x>y and a, x, y are all integers:
D = a * (10 ^ x) - a * (10 ^ y) =
= a * ((10 ^ x) - (10 ^ y)) = a * M
D is divisible by 9 if M is also divisible by 9.
M is always divisible by 9 for the same
reason the differences 1000-10=990 and 100-1=99 are all divisible by 9.

Let's say the three digit number in the beginning is xyz, we can write it as:
100x + 10y + z
The reverse will be:
100z + 10y + z
Subtracting will give us:
99x - 99z = 99(x-z)
This tells us that the difference is a multiple of 99, meaning a multiple of both 9 and 11.
This subtracted result is atmost a 3 digit number and dividing it by 11 would give us a 2 digit number. Let's say if we divide the subtracted result with 11, we get:
10a + b
Now, we know that given any number if it's divisible by 11, the reverse is also divisible by 11. Can be deduced easily by thinking what's the divisibility law for 11.
Also, reverse of any 3 digit multiple of 11 when divided by 11, gives the reverse of the 3 digit number itself divided by 11.
So, when we divide the reverse of "subtracted result" by 11, we would get the reverse if 10a + b, meaning:
10b + a
Now, in the magic we are adding the two reverses. The result of dividing the sum by 11 would give us:
10a + b + 10b + a = 11a + 11b
11a + 11b is once again divisible by 11.
This means that the final result(the sum of reverses) is two times divisble by 11 and also by 9(because it's divisible by 99). Which means the final result is divisible by:
11*11*9 = 1089.
Finally, we know that the sum of two 3 digit numbers can't exceed 1998, so it can't be a bigger multiple of 1089.
Hence, the answer is always 1089.

[@definitiveguide8137]

The phenomenon you're describing with the number 1089 is a well-known mathematical trick. It works with most three-digit numbers, as long as the first and last digits differ by at least two. Here's how it works:
Choose any three-digit number where the digits are not all the same (like 651).
Reverse the digits to form a new number (156 from 651).
Subtract the smaller number from the larger number (651 - 156 = 495).
Reverse the digits of this result (594 from 495).
Add this number to the original difference (495 + 594).
The final result is almost always 1089. This trick works because of the properties of number manipulation and digit rearrangement

Let the unique digits of the number be *x* , *y* , *z* in order.
So the number is:
*100x + 10y + z*
And the reverse of it is:
*100z + 10y + x*
Subtracting the reverse from original gives:
*99(x-z)*
If *x>z* let *t=x-z* ,
else let *t=z-x*
So the number we have, ignoring the sign, is:
*99(t) = 100(t) - t*
*= 100(t-1+1) - t*
*= 100(t-1) + 100 - t*
*= 100(t-1) + 10(9) +(10 - t)*
Possible values of
*t* : 1 to 9
*(t-1)* : 0 to 8
*(10 - t)* : 1 to 9
so they are single digits.
So the number we have is:
*100(p) + 10(9) + q*
where
*p = (t-1)*
*q = (10-t)*
The reverse of this number is:
*100q + 10(9) + p*
Adding these together, we have:
*101(p + q) + 180*
*= 101(t-1 + 10-t) + 180*
*= 101(9) + 180*
*= 1089*

Also if you do the first part where the subtraction happens, you can predict the result of the operation if you know the first or last digit of it. middle digit is always 9 and the sum of the other two digits is always 9. So in the example of the video we have 495, knowing 5 you can find 4 and construct 495. People will be surprised. The only case where this doesn't work is with 3 digit numbers where all digits are the same (eg 444, 888 etc)

[@vyshakreghukumar995]

Below is a very very long and rather convoluted mathematical explanation of this problem.
Let the first digit of the first number be a, second digit be b and third digit be c.
Then, first number = 100a + 10b + c
Reverse of this number= 100c + 10b + a
First number - its reverse
= 100a + 10b + c - (100c + 10b + a)
= 99a - 99c
= 99 (a - c)
The next set of calculations is to find the 3-digit formula of the above number.
= 99 (a - c - 1) + 99
= 100 (a - c - 1) - a + c + 1 + 90 + 9
= 100 ((a - c) - 1) + 90 + (10 - (a - c))
Thus, we have the first digit of the difference as (a - c) - 1, second digit as 9, and third digit as 10 - (a - c).
The reverse of the above number is =
100 (10 - (a - c)) + 90 + ((a - c) - 1)
Sum of the above 2 numbers
= 100 ((a - c) - 1) + 90 + (10 - (a - c))
+ 100 (10 - (a - c)) + 90 + ((a - c) - 1)
= 100(a - c) - 100 + 90 + 10 - (a - c) + 1000 - 100(a - c) + 90 + (a - c) - 1
= 1000 + 90 - 1
= 1089
One peculiar scenario where this rule might fail is when the difference of the first number and its reverse is 99.
E.g. 201 - 102 = 99
In this case, 99 + 99 = 198 which is not equal to 1089.
However if we consider 99 as a 3-digit number, that is 099, then we have 099 + 990 = 1089.
