Which is greater -3 or |-7|

|-7|

Step-by-step explanation: When an integer is written with vertical bars on either side, it means that we take the absolute value of that integer.

So |-7| is read as "the absolute value of negative 7."

The absolute value of an integer is its

distance from zero on a number line.

Think of absolute value in terms of a number line.

Since -7 is 7 units from zero, the absolute value of -7 is +7.

So now we are comparing -3 and +7.

Now obviously, positive numbers are always

greater than negative numbers.

So +7 is greater than -3 which means |-7| is greater than -3.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
