​Comparing Integers

​When comparing integers, we look at the value of the number. When we are dealing with positives, the bigger the number, the larger it is.

​

​When we are dealing with negatives, the more negative a number, the smaller it is. Numbers get smaller the further away from zero you go into the negatives.

​This means....

​70 > 56

​

​-2 < 40

​

​-10 < -3

​

​-64 > -150
