Question

I'm trying to help my sister with her 4th grade work but i'm not sure if i remember this type of work

Answer 1

`84*7`

Let's complete the boxes.

We split 84 into 80 + 4.

`84*7=(80+4)*7`

We multiplied 7 to the numbers inside the parenthesis.

`84*7=80*7+4*7`

Following EPMDAS, we do the multiplication part first.

`84*7=560+28`

Then, add.

`84*7=588`
