Best Hooda Math Tricks You Need to Know
1. The Multiplication Trick (Fast Multiplication by 11)
Multiplying numbers by 11 can be done in seconds using this trick. Here’s how:
- Take any two-digit number, say 52.
- Separate the digits: 5 and 2.
- Add them together: 5 + 2 = 7.
- Place the sum between the original digits: 572.
- So, 52 × 11 = 572.
For larger numbers, follow the same pattern but carry over if necessary. This trick saves time and enhances mental multiplication speed.
2. Squaring Numbers Ending in 5
If you need to square numbers ending in 5, follow this easy trick:
- Take the number, say 35.
- Remove the 5, leaving 3.
- Multiply 3 by the next number (4): 3 × 4 = 12.
- Attach 25 at the end: 1225.
- So, 35² = 1225.
This works for any number ending in 5! For example, 75² = 5625 (7 × 8 = 56, then add 25).
3. The Divisibility Rule Tricks
These simple tricks help determine whether a number is divisible by another without long division:
- If the last digit is an even number, it is divisible by 2.
- If the total of all digits is a multiple of 3, it is divisible by 3.
- If the last digit is 0 or 5, it is divisible by 5.
- If the sum of the digits can be evenly divided by 9, it is divisible by 9.
- If the difference between the sum of odd-positioned and even-positioned digits is a multiple of 11, it is divisible by 11.
Using these tricks, you can quickly determine divisibility without performing full division.
4. Mental Addition and Subtraction Tricks
Adding and subtracting large numbers mentally becomes simple with this method:
- Break the numbers into parts.
- Add or subtract from left to right instead of right to left.
- For example: 567 + 349
- Break it as: (500 + 300) + (60 + 40) + (7 + 9)
- Solve step by step: 800 + 100 + 16 = 916.
This method reduces errors and speeds up calculations.
5. The Trick for Quick Percentage Calculation
Finding percentages is often tricky, but here’s a shortcut:
- To find 10%, move the decimal one place left.
- To find 5%, take half of 10%.
- To find 20%, double the 10% value.
- Example: Find 35% of 240.
- 10% of 240 = 24
- 30% = 24 × 3 = 72
- 5% = 12 (Half of 24)
- 35% = 72 + 12 = 84
6. The Finger Multiplication Trick for 9’s Table
If you struggle with the multiplication table of 9, use your fingers:
- Spread out your hands.
- To multiply 9 × 3, bend your 3rd finger.
- The number of fingers on the left is the tens place (2), and the right is the ones place (7), making 27.
This trick works for 9 × any number up to 10 and is a fun way to memorize the table.
7. The Rule of 72 (Estimation for Doubling Money)
This trick is great for financial calculations:
- Divide 72 by the interest rate.
- The result tells how many years it takes for your money to double.
- Example: At 6% interest, 72 ÷ 6 = 12 years to double your investment.
This trick is widely used in finance and investing.
8. The Magic of Zero
Many people make mistakes when multiplying by zero. Remember:
- Any number multiplied by zero is zero.
- Any number raised to the power of zero is 1.
This simple rule helps avoid unnecessary calculation errors.
