Order of Operations with Parentheses* 2-24
Provide enrichment by using parentheses - a grouping symbol - to group numbers and operations explicitly. Simplify expressions inside any parentheses first. What's 9-(5-2)? First subtract 5-2 = 3. Then subtract 9-3 = 6. What's (9-2) - (3+1)? First subtract 9-2 = 7. Then add 3+1 = 4. Finally, subtract 7-4 = 3.
