🎮 Interactive BIDMAS Solver

Watch how we solve this expression step by step using BIDMAS!

3 + 4 × ( 2 + 1 ) ²

🌟 Worked Example

Calculate: 3 + 4 × (2 + 1)

Step 1 - Brackets first: (2 + 1) = 3

Step 2 - Then multiplication: 4 × 3 = 12

Step 3 - Finally addition: 3 + 12 = 15

Remember: BIDMAS order gives us the correct answer!

💪 Practice Exercises

1. Calculate: 6 + 2 × 5

2. Calculate: (7 + 3) × 2

3. Calculate: 20 - 3²

4. Calculate: 8 ÷ 2 + 1

5. Calculate: 4 × (6 - 2)

⚠️ Watch Out For These Common Mistakes!

❌ Doing operations left to right without following BIDMAS

Wrong: 6 + 2 × 5 = 8 × 5 = 40

✅ Right: 6 + 2 × 5 = 6 + 10 = 16 (multiply first!)

Remember: BIDMAS order overrides left-to-right reading!

❌ Forgetting to do brackets or indices first

Wrong: 3 + 4 × (2 + 1) = 7 × 3 = 21

✅ Right: 3 + 4 × (2 + 1) = 3 + 4 × 3 = 3 + 12 = 15

Always solve brackets first, then follow the rest of BIDMAS!

✨ Quick Summary

Follow BIDMAS to keep your calculations correct! Order of operations is essential in maths and computing—without it, calculations can give different answers!

✅ Brackets first - Always solve what's inside brackets
✅ Indices next - Calculate powers and roots
✅ Division & Multiplication - Work left to right
✅ Addition & Subtraction - Work left to right
✅ Never just work left to right - BIDMAS overrides this!

Remember: BIDMAS is the universal language of mathematics! ⚡
