## How to add natural numbers? Let's learn with an example:

### Stack the numbers on top of each other.

#### The tens digits line up in the next column to the left.

 4 8 + 8 5 ?

### Add the digits in the ones column:

#### 1 is the tens digit. Carry it over to the tens column. Write the digit above that column. Add it with the rest of the digits in that column.

 1 4 8 + 8 5 3

### Add the digits in the tens column:

#### 1 is the hundreds digit. Since there is no hundreds column... Write it down at the base, next to the tens digit.

 1 4 8 + 8 5 13 3
