(-5) [(-4) - (-2) + (-6) + 2 - 4 ]
Two negative signs cancel out to become a plus sign.
(-5) [(-4) +2 + (-6) + 2 - 4 ]
When adding two numbers with different signs, it's always larger minus smaller. Then copy the sign of the Larger number.
= (-5) [ -2 -4 -4]
In adding with similar signs, the sum will have the same sign.
= (-5) [ -10 ]
In multiplication, multiplying with same sign = positive. Otherwise, the product will be negative
= 50
Note: notice that I did the innermost part first, and worked my way out
