Question 954227: The answer to this equation:
0+50*1-60-60*0+10=?
My answer is 10. However, a friend is insisting the answer is 0. They arrive at 0 because they did the multiplication first. I was taught to only do brackeded sections first and that if there are no brackets or parenthises in the equation, then it must be approached left to right. My question is, isn't it correct to solve by performing each calculation from left to right? I have never heard of any rule that permits one to jump ahead directly to multiplication or any other calculation unless there are parenthisis or brackets in the equation.
