Think of a three digit number ...?

Question

... all of which are different (not 232, 866 or 555, for example)

Write the number you have on a piece of paper.
Under that, write the same number with the digits reversed.
Subtract the smaller of the 2 from the larger.
If the result is less than 100, double it.
Now, write that number down carefully
Under that, write the same number with the digits reversed.
Add the 2 numbers

What is the result?

Answer 1

Arithmetic Mathematics bear a certain trick that man can discover well. Like this:



532-235=297+792=1089

867-768=99*2=198+891=1089

321-123=198+891=1089



However, If you consider zero as a number and included in the digits, it will still be the same:



210- 012= 198+891=1089

650-056=594-495=99*2=198+891=1089



So there are high chances that the number will end up on 198 and it will always end up 1089. If one change occurs, the process and the results will be changed. This is how marvellous and mysterious mathematics really is. Wonderful!

Answer 2

1089

Answer 3

Answer 5

1. 312-213=99+99=198+891=1089

2. 864-468=396+396=792+297=1089



it comes out to be the same answer

Answer 6
