[tex]84\times7[/tex]

Let's complete the boxes.

We split 84 into 80 + 4.

[tex]84\times7=(80+4)\times7[/tex]

We multiplied 7 to the numbers inside the parenthesis.

[tex]84\times7=80\times7+4\times7[/tex]

Following EPMDAS, we do the multiplication part first.

[tex]84\times7=560+28[/tex]

Then, add.

[tex]84\times7=588[/tex]
