Question

Which of these is the algebraic expression for "4 less than the product of 3 and some number?"

4m − 3
3m − 4
3 − 4m
4 − 3m

Answer 1

B, product is multiplication so it is 3•m -4

Answer 2

The answer is D.

Explanation:

'4 less than the product of 3 and some number' is saying that the product of 3 and an unknown number m, is to be subtracted by 4. It would only make sense to say that it is 4 minus the product of 3 x m.

Remember,

Product = multiplication

Sum = addition

Subtraction = difference

Division = quotient.
