According to this rule, multiplication and division must always be done before addition and subtraction.
When we have both multiplication and division in the same expression, we simply solve them from left to right.
Let’s apply this rule directly to our math puzzle.
First, look at the division part: 90 ÷ 10.
When you divide 90
