it is actually a rather simple trick of standard math.

The base idea is to multiply your first 3 numbers by 10000 which leaves four zeros at the end input your last for numbers into.

This, however, mixes it up a bit. It uses a multiple of 20000 and then has you input your last four two times so when you do the final division by 2 you end up with your number

I could come up with hundreds of tricks like this in very little time.

All you have to do is work the math around what your goal is.
