Evaluate the absolute value of 24
minus nine plus the absolute value of 17 minus 20.
In order to evaluate, we must first
understand what this bars mean. They mean that we take the absolute
value of whatever is the inside, which means it will always be positive. 24 minus nine is 15, bring down our
absolute value bars. 17 minus 20 is negative three, and we’ll bring down those
absolute value bars.
So the absolute value of 15 means
we need to take the positive of 15, which is simply 15. Now the absolute value of negative
three is going to be positive three, because whether it’s negative three or positive
three doesn’t matter because when we take the absolute value, it will always be
positive. So now we need to take 15 plus
three, making our final answer 18.
