To solve an expression, you need to follow the order of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). Start by simplifying any expressions within parentheses, then evaluate any exponents, followed by multiplication and division, and finally addition and subtraction. If there are no parentheses or exponents, simply work from left to right, performing multiplication and division before addition and subtraction. Once you have simplified the expression according to the order of operations, you will have solved the expression. **
