subtract 7 from 2, then add the product of g and 8 to the result

Question

Help me its for school thank you

Answer 1

Subtract 7 from 2 would be written as 2 - 7

The comma and "then" tells you to do the 2 - 7 first, so (2 - 7) in paretheses

Product of g and 8, place the coefficient in front (2 - 7) + 8g

Answer 2

In mathematical notation

2 - 7 + 8g
