2 1x24=504

24x63= 15 12

42x36= 15 12

36x84=3024

63x48=3024

Write a few more groups:

1、23x96=2208

32x69=2208

2、3 1x39= 1209

13x93= 1209

I tell you, your inference is completely correct. By the way, X is a multiplication sign, and I can't type your multiplication sign on my keyboard.

One last request:

Can you set me as the best answer? Please.

Principle:

The product of one-bit multiplication is the same as that of ten-bit multiplication, and so are the numbers.
