Compare integers

Integers are positive and negative whole numbers:

...,-4,-3,-2,-1,0,1,2,3,4,...

Symbols are used to show how the size of one number compares to another. These symbols are:

a<b


COMPARING INTEGERS USING THE NUMBER LINE.

When comparing integers, you can use a number line

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.

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.


Compare 3 and -2

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

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

Compare -9 and 2
Solution: is less than
