5 ?  0

Since 5 is to the right of 0 on the number line, then 5 > 0.

First of all, .

Next we have .

Since both absolute values equal the same number ½, then .

-2   ?   2

Since -2 is to the left of 2 on the number line, then -2 < 2.

-3  <  -3

Since -3 is the same number as -3 and the statement includes where the two numbers are equal to each other, then this statement is true.

2  >  4

Since 2 is to the left of 4 on the number line, then 2  <  4.

So, the above statement is false.

-4 is less than 0.

Reading it left to right we get:

-4 is less than 0
-4  <  0

3 is not equal to -3.

Reading it left to right we get:

3 is not equal to -3

5 is greater than or equal to -5.

Reading it left to right we get:

5 is greater than or equal to -5.
5   >  -5
