***Move decimal to create a number between 1
and 10**

We started at the end of the number 123400 and moved it between the 1 and 2. That looks like a move of 5 places.

**What direction did it move?**

Looks like we moved it to the left.

**So, our count is +5.**

***Move the decimal 5 to the right**

***Move the decimal 13 to the left**
