Mastering Subtraction: All Tricks You Need for Fast Calculations
Subtraction is just as important as addition, yet many students struggle with it, especially when numbers get bigger or when borrowing is involved. But worry not! With a few smart tricks, you can subtract numbers quickly, mentally, and confidently.
In this guide, we’ll cover all possible subtraction techniques, from basic column subtraction to advanced mental math tricks.
Counting Up Method (Complement Method)
Instead of subtracting directly, count up from the smaller number to the bigger number.
This is useful for mental math.
Example: 74 – 39
• Start at 39
→ jump to 40 (+1)
→ jump to 74 (+34)
• Total difference = 1 + 34 = 35
Perfect for mental subtraction, especially when borrowing is tricky.
