Question

If y is 12 less than the product of a and b, then which of the following is an expression for y in terms of a and b ?

Answer 1

Answer: ab -12 

Given that y is 12 less than the product of a and b. 

The product of a and b is the multiplication of a and b:
a x b = ab

12 less than the product will mean that we need to take away 12 from ab, so 
y = ab - 12
