a. Multiplication and division are performed before addition and subtraction based on the order of operations. Following the order of operations ensures calculations are performed in a consistent and predictable way. b. Exponents are simplified when the calculation is fully simplified at the end, after all other operations are completed. Simplifying exponents too early could change the meaning of the expression or equation. It is best to wait until fully simplified. c. Context is important for determining the meaning and solution of equations. Additional context may be needed to interpret equations and expressions accurately.
