Does omitting the multiplication operator have an effect on order of operations When you write a mathematical expression like this:
$4:2(1+1)$,
does the fact that the multiplication operator is not explicitly written has any bearing on the precedence? What is the order of operations in this case?
Is it:
$4:4=1$ (order: parenthesized addition, implicit multiplication, division)
or
$2(1+1)=4$ (order division, parenthesized addition, implicit multiplication).
If the explicit operator has no effect, this would be $4\div2\cdot(1+1)$ and calculated from left to right (because of the no precedence between division and multiplication). Result woud then be $4$.

If the : means division, which i assume it does, then the 4 is divided by the expression 2(1+1). It is a fraction. Then you are free to divide the 4 in the numerator by the 2, then divide by the sum of 1+1, or multiply by 2 thru the denominator (and get 2+2), then add, and then divide, or add 1+1 first before the multiply thru by 2. In any case you get 2/2, or 4/4, =1.
