# Combination of Addition and Subtraction

We will discuss here about the combination of addition and subtraction.

The rules which can be used to solve the sums involving addition (+) and subtraction (-) together are:

I: First add and then subtract,

II: Solve the numbers enclosed in the brackets and then solve further.

Solved example involving addition (+) and subtraction (-) together:

1. Solve 3252 - 1802 + 2610

Solution:

3    2    5    2

+  2    6    1    0

Now

5       8    6   2

-   1    8    0    2

4    0    6    0

2. Find the solution to (7259 - 5369) + 2156

Solution:
