Annabelle and navene are multiplying (4275)(4372). annabelle's work navene's work (4275)(4372) = 42 + 375 + 2 = 4577 (4275)(4372) = 42⋅375⋅2 = 46710 is either of them correct? explain your reasoning. you get (30) points if you answer within 20 min

Neither are correct.

Navene has broken the problem up and simply added numbers together to get "4577"

Annabelle is also wrong because whereas she multiplied, she also broke up the numbers in the equation to get "46710"

The answer should be 18,690,300

(4275)(4372) = 42 + 375 + 2 = 4577

Here, annabelle just "broke" the numbers and add them, you can't do this in multiplication (or in any operation really)

(4275)(4372) = 42⋅375⋅2 = 46710

Navene also "broke" the numbers, the only difference is that she multiplied them, but this is still wrong

solving the multiplication:

(4275)*(4372) = (4000 + 275)*(4000 + 372) = 4000*4000 + 275*4000 + 372*4000 + 275*372 =18690300

there i splitted a kinda hard multiplication in 4 simpler ones that are much easier to solve.

i used to know but i learned it a long time ago sorry
