Solve Multi-Step Expressions!

Using Order of Operations

Grade 5 Ontario Math πŸ“š β€’ Operations

Hello my wonderful Grade 5 superstar! πŸ‘‹

I'm Kashef and today we're solving Multi-Step Expressions! These have lots of operations (+, βˆ’, Γ—, Γ·) and brackets. We follow the correct order so we get the right answer every time. Ready to become a master of mixed operations? Let’s go! πŸš€

πŸ“‹ Order of Operations (BEDMAS)

Brackets first
Exponents (we'll skip today)
Division and Multiplication (left to right)
Addition and Subtraction (left to right)

✍️ Step-by-Step Examples

Example 1: 12 + 6 Γ— 3

12 + 18 = 30

Example 2: (12 + 6) Γ— 3

18 Γ— 3 = 54

Example 3: 20 βˆ’ 4 Γ— 2 + 6

Multiply first: 4 Γ— 2 = 8
20 βˆ’ 8 + 6
12 + 6 = 18

🎯 Let’s Practice Multi-Step Expressions!

1. 15 βˆ’ 3 Γ— 2 + 4

15 βˆ’ 6 + 4 = 13

2. (8 + 12) Γ· 4 Γ— 3

20 Γ· 4 Γ— 3 = 15

3. 36 Γ· 6 + 5 Γ— 2

6 + 10 = 16

πŸ›’ Real-Life Word Problems

Problem 1: You buy 3 notebooks for $4 each and 2 pens for $3 each. How much do you spend total?

(3 Γ— 4) + (2 Γ— 3) = 18

Problem 2: A pizza costs $24. You and 3 friends share it equally after eating 6 slices total. How much does each person pay if there are 12 slices?

(24 Γ· 12) Γ— 6 = 12 slices eaten β†’ remaining cost shared: but simpler: total $24 for 4 people = $6 each
