For example, 70-1 is the same as 1 / 70+1. Similar for any other negative power. For the remainder of the problem, you simply have to add fractions.
There's nothing to solve, it's simply an expression.
It is: -16+(-14) = -30
7 + (-30) =7 - 30 = -23
40+-30=10
30
When any number is divided by a negative number the result is negative. So, 120 / -4 = -30
It does not help you.
