D → Division
M → Multiplication
A → Addition
S → Subtraction
🔷 Simplification Problems
Q1. 25 × 4 + 10
= 100 + 10 = 110
Q2. 100 ÷ 5 × 2
= 20 × 2 = 40
Q3. 50 + 20 × 3
= 50 + 60 = 110
Q4. (40 + 60) ÷ 5
= 100 ÷ 5 = 20
Q5. 200 − 50 × 2
= 200 − 100 = 100
Q6. 64 ÷ 8 + 12
= 8 + 12 = 20
Q7. 36 × 2 − 10
= 72 − 10 = 62
Q8. (20 + 30) × 2
= 50 × 2 = 100
Q9. 144 ÷ 12 × 3
= 12 × 3 = 36
Q10. 80 − (10 × 5)
= 80 − 50 = 30
🔷 Approximation Tricks
Q11. 498 + 302
≈ 500 + 300 = 800
Q12. 999 × 48
≈ 1000 × 48 = 48000
Q13. 203 × 49
≈ 200 × 50 = 10000
Q14. 798 ÷ 4
≈ 800 ÷ 4 = 200
Q15. 52 × 19
≈ 50 × 20 = 1000
🔷 Advanced Simplification
Q16. 25 × 16
= 400
Q17. 125 × 32
= (32 ÷ 8) × 1000 = 4000
Q18. 99 × 84
= 8400 − 84 = 8316
Q19. 48 × 48
= (50−2)² = 2304
Q20. 75 × 96
= (100−4) × 75 = 7200
