When a math problem has lots of operations, we solve them in a special order so everyone gets the same answer. That special order is called PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Remember, multiplication and division work as a team from left to right, and the same goes for addition and subtraction. Ready to test your knowledge? In Part 1 of the challenge, decide where the parentheses should go to make each number sentence true. Then in Part 2, figure out the missing operation signs and parentheses to complete each equation. All done? Great work!
