Question

R and (-4) are added and their sum is subtracted from half of their product

Answer 1

R + 4

Explanation:

we make calculations as the question indicates

R + -4

= R - 4

we need to find their product

= R X 4

= 4R

we get half of the product

1/2 x 4R

= 2R

we now make the substraction

2R - (R-4)

= 2R - R + 4

= R + 4
