You can put this solution on YOUR website! The notation is tricky. Double check to see that you typed in what you intended. This is what I think you intended, if I'm wrong let me know:
The absolute value of -4 times the absolute value of -7 minus 3 times the absolute value of -6.
|-4|*|-7|-3|-6|
(4)*(7)-3(6)
28-18
10
Happy Calculating!
