Ah, what a happy little math problem we have here! If you take 640 and divide it by 8, you'll find the answer you're looking for. Just like painting a beautiful landscape, sometimes all it takes is a little bit of patience and gentle calculation to reveal the hidden beauty within the numbers.
(88-8)x8= 640
80 x 8 = 640
640 ÷ 8 = 80.
640 ÷ 8 = 80
(160 × 8), (256 × 5), (320 × 4), (640 × 2)
20 :)
80 x 8 = 640
640 ÷ 8 × 6 = 480
You can fit 8 79s in 640. To figure this out, divide 640 by 79. 640 divided by 79 equals 8.08, so 8 79s will fit in 640.

32*20 320*2 8*80 160*4 10*64
Twenty times thirty-two equals 640.
