Question

Annabelle and Navene are multiplying (4275)(4372).

Annabelle's Work
(4275)(4372) = 42 + 375 + 2 = 4577 (4275)
Navene's Work
(4372) = 42⋅375⋅2 = 46710
Is either of them correct? Explain your reasoning.

Answer 1

neither one right?

Answer 2

yeah neither of them are right

I have no idea what they're trying to do

Answer 3

Neither one because they are supposed to do first is (42 * 75) * (43 * 72). then they are supposed to do convert 42 and 75 to non exponent numbers, then multiply the answers (for 42 and 75 into a non existent number so each of their answers times the other), then do the same for 43 and 72. Then the final step is to multiply the last two final answers and your done! ({42*75}*[43*72] = your answer!)
