10 divided by 10 is 1, not 10.

10+10-10*10you missed this>>>/10=
now you do this in order:
10+10-[(10*10)/10]=
so, 10*10 = 100; 100/10 = 10.
it's a stupid game i've known since i was 5 to impress your friends, aritmetically it's so obvious that it's made of two parts: add and substract the same number, the substraction number is made of the same number being multiplicated and divided by the same number...

Simple:
1. 10x10 = 100
2. answer at 1 : 10 so that makes 100 : 10 = 10 (note that these two steps cancel eachother out)
3. then, 10 + 10 = 20
4. answer at 3 minus answer at 2 makes 20-10 = 10
If you take all these steps at once you will get this:
(number) x 2 - (number) = (number, yes always)
1. 10x10 = 100
2. answer at 1 : 10 so that makes 100 : 10 = 10 (note that these two steps cancel eachother out)
3. then, 10 + 10 = 20
4. answer at 3 minus answer at 2 makes 20-10 = 10
