Question

Paulo used the expression 7×(4+4) to solve 7×8. Does his method make sense? Explain​

Answer 1

Yes.

Explanation:

This is because if using PEMDAS, you will see that (4+4) = 8.

That would mean that 7x(4+4) =7x8, and that Paulo is correct.

Answer 2

Yes, because 4 + 4 = 8 so it is the same as 7 × 8.
