If a times b equals 260, then a times 2B equals several, 3A times b equals several, a times (b divided by 2) = several (a divided by 4) * (b * 4)=
The decimal point has learned how to add and subtract

=260*2=520
=3*260=780
=260/2=130
=260/4*4=260
It's all about the commutative law of multiplication
