What is the difference? |-9| - |13| =?
A)-22
B)-4
C)4
D)22
To solve this problem, you need to understand the concept of absolute value and subtraction.
The absolute value of a number is its distance from zero on the number line, expressed as a positive value. The absolute value is represented by the | | symbols.
In this problem, we have |-9| - |13|. So, we need to find the absolute value of -9 and the absolute value of 13, and then subtract them.
The absolute value of -9 is 9, and the absolute value of 13 is 13. So, |-9| - |13| is equivalent to 9 - 13.
Now, subtracting 13 from 9 gives us -4.
Therefore, the correct answer is B) -4.
