Determine the absolute value of −13
.
Explain how you could use a number line to determine the absolute value of −13
.
The absolute value of −13 is 13, since absolute value represents the distance a number is from zero, regardless of whether it is positive or negative.
To use a number line to determine the absolute value of −13, you would start at zero on the number line and count 13 spaces to the left, as negative numbers are found to the left of zero on a number line. The 13th space you land on is the number that has an absolute value of 13, which is positive 13.
To determine the absolute value of -13, you can use a number line by following these steps:
Step 1: Locate the number 0 on the number line.
Step 2: Draw an arrow to the left from 0 to represent the negative numbers.
Step 3: Count 13 units to the left from 0.
Step 4: When you reach -13, mark it on the number line.
Step 5: The absolute value of -13 is the distance between 0 and -13, which is 13 units.
Step 6: Therefore, the absolute value of -13 is 13.
