Dan Sloughter (Furman University) The Rhind Papyrus September 13, 2006 3 / 14I Note: this follows from
45×53 = (1+4+8+32)×53 = 1×53+4×53+8×53+32×53.
Example: multiplication
I Ahmes would compute 45×53 = 2385 as follows:
\ 1 53
2 106
\ 4 212
\ 8 424
16 848
\ 32 1696
Total 45 2385

Dan Sloughter (Furman University) The Rhind Papyrus September 13, 2006 4 / 14Example: division
I Ahmes would compute 437÷23 = 19 as follows:
\ 1 23
\ 2 46
4 92
8 184
\ 16 368
Total 19 437

2).
