Question

M–[(m–n)÷(−2)](−5), if m=−4, n=−6

Answer 1

-9

Explanation:

Answer 2

-9

Explanation:

We are given the expression m–[(m–n)÷(−2)](−5). Substituting -4 for m and -6 for n, we get:

-4–[(-4 + 6)÷(−2)](−5)

We must do the work that appears inside parentheses first:

-4–[( 2 )÷(−2)](−5)

Next we must do the work that appears inside square brackets:

-4–[ -1 ](−5)

Multiplication comes next. The above expression becomes:

-4 - [ 5 ]

which in turn comes out to -9
