In this post, we are going to learn a strategy for **adding two consecutive numbers**, or in other words, numbers that are one value apart. And a strategy for** adding numbers that are two values apart.**

### Adding Strategy: adding two consecutive numbers

This strategy consists in first doubling the smaller number then adding one to the answer.

For example: 8 + 9

We double 8, which is the smaller number: 2 x 8 = 16

We add 1 to the answer: 16 + 1 = 17

So, 8 + 9 = **17 **

### Adding Strategy: adding numbers that are two values apart

Now, we are going to take a look at how to add numbers that are separated by two values. In this example, we’ll need to find the median value of the two numbers and then double it.

For example: 12 + 14

First, we need to find the median value of the two numbers which in this case, is the number 13.

Now, let’s double that number: 2 x 13 = 26

So, 12 + 14 = **26**
