Answer:
<u> 800 20 1 </u>
50<u>| | | |</u>
4 <u>| | | |</u>
pretty much a rectangle with 800 20 1 at the top
50 4 on the side
and split the numbers in the box - i tried to recreate it as much as possible
oh then in each little box you have to multiply the numbers so
50 x 800 = 40,000 in the box
50 x 20 = 1,000 in the next box
50 x 1 = 50 in the next box
4 x 800 = 3,200
4 x 20 = 80
4 x 1 = 4
then you add all of them which would be 44,334
