Today we will talk about mental maths. Mental maths means the calculation of maths within seconds and solving the problem without any pen and paper. And students who know mental math are perfect in maths and make very few mistakes. solve the problems much faster.

(A)Mental math is a process in which children or humans calculate everything without paper, pen, and calculator in seconds

(B)Mental math is a kind of quality that let people and students solve math “in their mind” without pen paper or a calculator.

### Mental Math Practice Examples

In mental mathematics, calculations are done without any equipment or copy or pen. To understand it better, methods have been suggested which are as follows:

**Think carefully and understand the problem:**After reading the question, make sure that you have understood the question well or thought well about its answer. There can be difficult questions related to adding, subtracting multiplying, and dividing.

Identify the main numbers and pay primary attention to the numbers involved and their relations.**Divide problems into several parts:**

Simplify difficult problems.

Divide big problems into small, simple parts.

Try to solve the question by making big numbers easy by using place value.

**3. Use Strategies and Techniques**

Add: Addition from left to right: First, we need to add the bigger place value. Like, for 57 + 68, first add 50 + 60 = 110, then add 7 + 8 = 15, finally add 110 + 15 = 125.

Rounding and compensation: Round the numbers to the nearest ten or hundred, then solve. For example, to add 59 + 33, round 59 to the nearest 60 and round 33 to the nearest 30. 60 + 30 = 90, then solve: 90 – 1 + 3 = 92.

4. **Subtraction:**

Complementary numbers:

Use complementary numbers. like, for 1000 – 358, find the complement of 358 to 1000, which is 642.

5. **Multiply:**

Break down multiplication: Try using the distribution method. For example, for 43 × 6, think of 43 as 40 + Therefore, (40 × 6) + (3 × 6) = 240 + 18 = 258.

Doubling and halving: For example, suppose one number is even or the other number is odd, then halve the even number or double the odd number. For example, 16 × 35 would be 8 × 70 = 560.

7. **Division:**

Estimate: Think about the quotient. like, for 184 ÷ 8, multiply 164 by 160 (a multiple of 8), 160 ÷ 8 = 20.

184 – 160 = 24,

24 ÷ 8 = 3, and

184 ÷ 8 = 20 + 3 = 23.
