Simplification – Speed Tricks & Tough Problems
Master fast calculation techniques to solve simplification questions within seconds.
1. Important Rules (BODMAS)
- Bracket → Order → Division → Multiplication → Addition → Subtraction
- Solve brackets first
- Division and multiplication left to right
2. Speed Tricks
- Use approximation when options are far apart
- Memorize squares (1–30)
- Memorize cubes (1–20)
- Convert division into multiplication
3. Tough Problems
Q1: (48 ÷ 6 × 5) + (36 ÷ 9 × 4) = ?
Solution:
48 ÷ 6 = 8 → 8 × 5 = 40
36 ÷ 9 = 4 → 4 × 4 = 16
Total = 40 + 16 = 56
Q2: √144 + 12 × 3 − 6² = ?
Solution:
√144 = 12
12 × 3 = 36
6² = 36
12 + 36 − 36 = 12
Q3: (25 × 4) + (81 ÷ 9) − 7² = ?
Solution:
25 × 4 = 100
81 ÷ 9 = 9
7² = 49
100 + 9 − 49 = 60
Q4: (64 ÷ 8 × 7) − (49 ÷ 7 × 3) = ?
Solution:
64 ÷ 8 = 8 → 8 × 7 = 56
49 ÷ 7 = 7 → 7 × 3 = 21
56 − 21 = 35
Q5: (36 × 5 ÷ 6) + (72 ÷ 8 × 2) = ?
Solution:
36 × 5 = 180 → ÷ 6 = 30
72 ÷ 8 = 9 → × 2 = 18
30 + 18 = 48
4. Exam Tips
- Never solve randomly — follow BODMAS
- Check options for approximation
- Practice daily for speed improvement
- Focus on accuracy first, then speed
