Hello my wonderful Grade 5 superstar! πŸ‘‹

I'm Kashef and today we're learning how to use Brackets (Parentheses)! Brackets tell us what to do first in a math problem. They are like special instructions that keep everything in the right order. Ready to become an Order of Operations expert? Let’s go! πŸš€

🧠 The Rule: Brackets First!

Always do what’s inside the brackets first!

3 + (4 Γ— 5) = 3 + 20 = 23
(3 + 4) Γ— 5 = 7 Γ— 5 = 35

✍️ Examples

Example 1: 20 - (6 + 3) = ?

20 - 9 = 11

Example 2: (15 + 9) Γ· 3 = ?

24 Γ· 3 = 8

Example 3: 5 Γ— (8 - 2) + 4 = ?

5 Γ— 6 = 30 β†’ 30 + 4 = 34

🎯 Let’s Practice!

1. 12 - (5 + 3) = ?

4

2. (9 + 6) Γ— 4 = ?

60

3. 30 Γ· (10 - 4) = ?

πŸ›’ Real-Life Word Problems

Problem 1: You have 50 points. You lose (4 + 6) points and then gain 20 points. What is your final score?

50 - 10 + 20 = 60 points

Problem 2: A box has (8 + 5) toys. There are 4 boxes. How many toys total?

13 Γ— 4 = 52 toys
