**Trick:**

In addition, adding 10 to a two digit number is easy as we just need to increase the digit in the tenth place by 1. 12 + 10 is 22,34 + 10 is 44 and so on.

We use the same rule while adding any two numbers.To be clear, see how 71 and 69 is added

**Method 1:**

**Step 1:**

71 + 69 can be written as **71 + 70 -1**

In this step, 69 is split as 70 and 1

**Step 2:**

Addition of 71 + 70 is easy which gives 141 ie ** 71 + 70 = 141**

Now subtract 1 from 141 ie **141 - 1 = 140**.

This gives the answer i.e. **71 + 69 = 140**

**Method 2:**

Alternatively, the below method can also be used.The choice of method depends on the numbers that are added

**Step 1:**

71 + 69 can be written as **71 + 60 + 9**

In this step, 69 is split as 60 and 9

**Step 2:**

Addition of 71 + 60 is easy which gives 131 ie ** 71 + 60 = 131**

Now add 9 to 131 ie **131 + 9 = 140**.

This gives the answer i.e. **71 + 69 = 140**
