Order of Operations with Rationals
Grade 7 · Math · Operations with Rational Numbers · British Columbia, Canada
Lesson Summary
Apply the correct order of operations when working with rational numbers.
Explanation
The order of operations (often remembered as PEMDAS) tells you to handle Parentheses first, then Exponents, then Multiplication and Division from left to right, and finally Addition and Subtraction from left to right. When rational numbers include negatives, fractions, or decimals, the rules stay the same. Always simplify inside grouping symbols first before moving outward.
Practice Questions
Q1: Evaluate: 3 + 2 × (−4).
Answer: Multiply first: 2 × (−4) = −8. Then add: 3 + (−8) = −5.
Q2: Evaluate: (−6 + 2)² ÷ 8.
Answer: Parentheses first: −6 + 2 = −4. Exponent: (−4)² = 16. Divide: 16 ÷ 8 = 2.
Q3: Evaluate: −1/2 × (4 − 10) + 3.
Answer: Parentheses: 4 − 10 = −6. Multiply: −1/2 × (−6) = 3. Add: 3 + 3 = 6.
