Question 548840
Since the absolute value is a grouping symbol, like parentheses, you have to calculate it first
{{{4(-6)-abs(-2-4(-2))=4(-6)-abs(-2-(-8))=4(-6)-abs(-2+8)=4(-6)-abs(6)=4(-6)-6}}},
but within the absolute value you multiply first to find the product of 4 times (-2), because multiplication has priority over addition and subtraction.
After this point, multiplying 4 times (-6) must be done before subtracting 6, so
{{{4(-6)-abs(-2-4(-2))=-24-4=-28}}}
If your teacher objects to having more than one equal sign on a line, just do it your teacher's way.
