Additions and Subtractions |

Solving problems of additions and subtractions separately are very easy. Some problems are containing additions and subtraction combine. These problems are very tough to solve in a single attempt. By splitting solving of addition and subtraction problems will take a lot of time. Without implementing the BODMAS rules, the result will not be sure. You can find in the picture what is correct method to solving problems in a speedy way in competitive exams.

BODMAS rules should implement to solve this Addition and subtraction problem. What are the BODMAS Rules?.

**stands for Bracket, Of, Division, Multiplication, Addition and Subtraction. By applying the BODMAS rules, simplification of the problems will be done in an easy way.**

*BODMAS*
The candidates should solve addition & subtraction problem in a single attempt.

**. While doing Addition & Subtraction problems, don't use paperwork.**__Do not split and not do two times__
For Example:

**7652 - 3216 - 2215 = ?**
Step I:

Add the last digit of the last number with the last digit of the second number and subtract the result digit with the last digit of the first number.

**7652 - 3216 - 2215 = 1**Add the last digit of the last number with the last digit of the second number and subtract the result digit with the last digit of the first number.

i.e. 5 + 6 = 11Step II:

Keep 1 in mind for further calculations.

The result 1. Subtract 1 from the last digit of the first number.

2-1= 1

Write 1 as final answer digit.

**7652 - 3216 - 2215 = 21**

Add the second digit of the last number with the second digit of the second number and add 1 which is in mind.

i.e. 1 + 1 = 2

2 + 1 = 3 ()1 is from the previous calculation

The result is 3. Subtract 3 with the second digit of the first number.

5 - 3 = 2

Write 2 as final answer second digit.

Step III:

**7652 - 3216 - 2215 = 221**

Add the third digit of the last number with the third digit of the second number. The result 4 subtract from the third digit of the first number.

i.e. 2 + 2 = 4

The result is 4.

Subtract 4 from the third digit of the first number.

6-4 = 2.

Write 2 as final answer third digit.

Step IV:

**7652 - 3216 - 2215 = 2221**

Add the fourth digit of the last number with the fourth digit of the second number. The result 5 subtract from the fourth digit of the first number.

i.e. 3 + 2 = 5

The result is 5.

Subtract 5 from the fourth digit of the first number.

7-5 = 2

Write 2 as final answer fourth digit.

The answer for the problem is

**7652 - 3216 - 2215 = 2221.**

Practice:

- ? - 26871 - 36141 = 18420
- 81432 - ? - 36141 = 18420
- 81432 - 26871 - ? = 18420
- 81432 - 26871 - 36141 = ?
