12 Maths Tricks for Quick Calculation | Maths Magic Tricks | Examples | |

## 12 Maths Tricks (With Examples)

Imagine how mathematics would be easy and interesting when you have the ability to calculate the problems in a matter of seconds using some Maths tricks. There are different kinds of arithmetic operations like addition, subtraction, division, multiplication, squaring, roots, powers, logarithms, divisions, etc. Here are some of the best tricks, which will help students to perform arithmetic calculations easily.

### 1. Maths Tricks for Addition

With the help of basic principles of tens and unit places, the addition of two-digit numbers is performed by

- Take 43 + 34
- Split the second number into tens and unit places. 34 = 30 + 4
- Finish the ten’s addition. 43 + 30 = 73
- Finally, add the remaining unit place digit. 73 + 4 = 77.

### 2. Maths Tricks for Subtraction

Here is an example that requires a lot of borrowing

- Consider two numbers say 1000 and 676
- Subtract 1 from both the numbers; we get 999 and 675
- Then subtract 675 from 999, we get 324
- So, 1000 – 676 = 324.

### 3. Quick Multiplication Tricks by Breaking Down Numbers

- Let’s try the numbers 24 and 16
- First split the number 24, which gives 4 x 6
- Then multiply 6 with 16, we get 96
- Finally multiply the number, 96 x 4 = 384
- So, the multiplication of two numbers 24 x 16 gives the solution 384.

### 4. Multiplied By 15

- Consider the multiplication of two numbers say 56 and 15
- Now add zero at the end of the first number, it becomes 560.
- Divide that number by 2; we get 560/2 = 280
- Add the resultant number with 560, so 560 + 280 = 840.
- So the answer for 56 and 15 is 840.

### 5. Multiplication of Two-Digit Numbers

If anyone of the given numbers is an even number, then follow the steps to solve

- Consider an example, 18 x 37
- Here 18 is an even number, then divide the first number in half, so that 18/2 = 9
- Then double the second number. 37 x 2 =74
- Finally, multiply the resultant numbers. It becomes 74 x 9 = 666

### 6. Maths Division Tricks

The numbers that can be evenly divided by certain numbers are:

- If a number is an even number and ends in 0, 2, 4, 6 or 8, it is divided by 2.
- A number is divisible by 3 if the sum of the digits is divisible by 3. Consider the number 12 = 1 + 3 and 3 is divisible by 3.
- A number is divisible by 4 if the last two digits are divisible by 4. Example: 9312. Here the last two digits are 12, and 12 is divisible by 4.
- If the last digit is 0 or 5, it is divisible by 5
- If a number is divisible by 2 and 3, then it is divisible by 6, since 6 is the product of 2 and 3.
- If the number is divisible by 8, the last three digits of the numbers are divisible by 8.
- If a number is divisible by 9, the sum of the digits is divided by 9. Let us consider the example, 4518 = 4 + 5 + 1 + 8 = 18, which is divisible by 9.
- If the final digit of the number is 0, it is divisible by 10.

### 7. Maths Trick to Find Percentage

Let us take; we have to find the percentage of the number 5% of 475, follow the steps.

- For the given number, move the decimal point over by one place. 475 becomes 47.5
- Then divide the number 47.5 by 2, we get 23.75.
- 23.75 is the solution to the given problem.

### 8. Maths Magic tricks to Calculate Squares ending with digit 5

- Let’s consider the number 75 to find its square.
- Start writing the answer of last two digits number that is 25 because any number that ends with 5 is 25
- Take the first digit of the number 75. That is 7 and take the number that follows 7 is 8.
- Now, multiply 7 and 8, we get the number 56.
- Finally, write the number 56 in the prefix and combine with 25 what we already wrote.
- So, the answer is 5625.
- Squares Ending in 5: n5 = n(n + 1)52 = n(n + 1)25 , where n is the first digit.
- Example: Let’s consider the number 75 to find its square. Here n = 7,

So, 75 = 7(7 + 1)25 = (7 x 8) 25 = 5625.

### 9. Tricks to Multiply by 2 and 4

When a number is multiplied by 2 or 4, then the last digit of the resulting value will be an even number always.

**Examples:**

- 19 x 2 = 38
- 19 x 4 = 76

### 10. Multiplication by 5

When a number is multiplied by 5, then the resulting value will either end with 0 or 5.

**Examples:**

- 11 x 5 = 55
- 8 x 5 = 40
- 121 x 5 = 605

### 11. Multiplication by 10

When a number is multiplied by 10, then the resulting value ends with 0 always.

**Examples:**

- 5 x 10 = 50
- 10 x 10 = 100
- 11 x 10 = 110
- 17 x 10 = 170
- 211 x 10 = 2110

### 12. Tricks to Memorise Table of 9

It is easy to remember the table of 9. Just we need to focus on the pattern.

09, 18, 27, 36, 45, 54, 63, 72, 81, 90

We can see the numbers at the ten’s place are increasing by 1, and the numbers at the unit place are decreasing by 1.

### Conclusion

Maths is a fun subject. Adding tricks to this subject will make it more interesting. Students will be able to solve all the complex problems using these Maths magic tricks. These tricks also help students to improve their problem-solving skills and boost their confidence.

## Frequently Asked Questions on Maths Tricks

### What is the use of maths tricks?

### What are multiplication tricks?

### How to add in a faster way?

Firstly, round up both the numbers by adding or subtracting small numbers.

Add the numbers.

Now subtract or add those values to get the final result.

For example, Add 799 and 299.

Round up 799 to 799+1 = 800 and 299 to 299+1 = 300

800+300 = 1100

Now subtract the added numbers from 1100,

1100-1-1 = 1100-2 = 1099

### How to multiply quickly?

Splitting the number 81 = 8 x 9

Multiply 24 by 8, 24 x 8 = 192

Now multiply 192 x 9 = 1728

Hence, the multiplication of numbers by one digit number is easier.
