    i know order of operations is par thesis 1st... so it becomes \[6\div 2(3)\] but then isnt it multiplication 1st then division? or arent they on the same level? or does that parenthesis around the 3 make any change?.... ive heard stories now

    We can follow, PEMDAS or BODMAS.

    BODMAS means Bracket of division multiplication addition and subtraction.

    so basically \[6\div 2(3) = 6\div 2 \times 3\]

    when you have only multiplications and division, the order of evaluation is from left to right. and a(b) is ecactly same as a*b.

    multiplication and division have exactly equal priorities.
