You can both compare and order integers by subtracting them:
- If the difference is zero, as the name suggests...there's no difference! So, the integers are the same. For example, you have
- If the difference is positive, then the first integer is bigger than the second. For example:
and we deduce that 5 is greater than 2, 18 is greater than -2 and -3 is greater than -10
- If the difference is negative, then the first integer is less than the first. For example, if we invert the previous differences, we have
and we deduce that 2 is less than 5, -2 is less than 18 and than -10 is less than -3
