Multiplication works both ways
A×B is the same as B×A
Any number A multiplied by another number B is the same as B multiplied by A.
This makes many multiplications much easier because, for instance, it is easier to multiply
2×8=8+8=16
Than 8×2=2+2+2+2+2+2+2+2=16
Example 1
8×4=4×8=8+8 then 2×16=32
Example 2
6×7=7×6=6×6+6=36+6=42
