I could be wrong but it only works when the first digit is the same.
so 24 × 27 would work but 12 × 26 wouldn't
24 × 27
(24 + 7) × 20 or you could do (24 + 7) × 2 × 10 = 620
4 × 7 = 28
620 + 28 = 648

55x17=?
55+7=62
62×10=620
5×7=35
620+35=655
but 55x17=935

Maybe I’m not understanding something form most works, but for 99*87 or 92*57 I can’t make it work

I don't really understand
maybe you should do 35x22, 99x99, 57x68.

89 x 24 = (89+ 4) x 10 x 2 = 1860 + 9x 4= 1860+ 36 = 1896 not 2136 what am I missing?

This method works only if the first digit of both the numbers are the same.
