What is the value of |45-75|

Answer: + 30

Step-by-step explanation: Before jumping right into this problem, let's just review quickly what the vertical bars mean around 45 - 75.

The vertical lines are called absolute value and we use them around either side of the number. Absolute value means distance from zero on a number line. This will be very important to understand when doing this problem.

Before taking the absolute value of a number, always simplify what's inside the absolute value as much as possible.

So here we have |45 - 75| inside the absolute value which can be thought of as |45 + - 75| or - 30. So we have |-30| which is + 30.

Remember that absolute value means distance from zero on a number line so the absolute value of - 30 would be 30 because - 30 is 30 units from zero on the number line.

This means that |45-75| is + 30.
