In the Order of Operations we learn that we work the operations of multiplication and division before the operations of addition and subtraction. The order of operations is Parenthesis Exponents Multiplication and Division from left to right Addition and Subtraction from left to right. If grouping symbols are used such as parentheses perform the operations inside the grouping symbols first.
For operations on the same level solve from left to right.
But when solving equations we do the exact opposite. Type in your sum to see how to solve it step by step. For math to work there is only one order of operations to evaluate a mathematical expression. 5 3 5 5 5 125.
