48÷2(12) = 2(12) without a "x" sign means that this multiplication is the next step in the equation. Every time. No exception. You can't just drop the parenthesis at will and replace it with "x". Basic algebra.

Paul, by using that reasoning you are making the claim that division is associative
post #539
division is not associative, you cannot add parentheses as you can w/ multiplication
1*2*x = (1*2)*x = 1*(2*x) =1(2*x) = 1(2x) = 1*(2x) because multiplication is associative
but if any of the multiplications in those expressions are changed to division then they are all mostly different
