Comparing integers


When comparing integers, you can use a number line
.

numberline-image

Any number to the right of 0 gets bigger and bigger as you move to the right.

So, if the numbers are positive, the smaller number is the one closer to 0

numberline-image

Any number to the left of 0 gets smaller and smaller as you move to the left.

So, if the numbers are negative, the bigger number is the one closer to zero

Thing to remember:

Numbers on the left are always smaller than numbers on the right.

Example #1

Compare 3 and -2 numberline-image

-2 is on the left of 3, so -2 is smaller than 3


Example #2

Compare -4 and -1

At first, you may have a tendency to say that -4 is bigger than -1 because 4 is bigger than 1.

However, this is not the case. -1 is bigger than -4 because it is closer to 0.

Also, -1 is on the right of -4
