Question
|-x-a|-a(-x) if a=-3 x=-4
7+3(-4)
10(-4)=-40
If its not correct please explain step by step Sorry I am no good at math
Hi,
I'm going to use ABS(x) for |x|.
ABS(-(-4) - (-3)) - (-3)(-(-4))
ABS(4+3) - (-3*4)
7 + 3(4)
Do all multiplication before any additions.
7 + 12
=19
Remember to follow the order of operations.
1. Parenthesis
2. Exponents
3. Multiplication/division
4. Addition/Subtraction
Let me know if you have any questions.

| Comment | Bobby, Thank you, #1 and #2 explanation are very clear now that you explained it. Reading your response to #2 made me realize that the pendulum was not 1/3 into the swing, but 1/3 the lenght of the pedulum. Even, so I still would not have figured this one out. Thanks, Adrienne | ||
