# Add the numbers: 293 + 290 + 313 + 345 = ? Calculate the natural numbers sum and learn how to do the addition, column adding method, from right to left

## The numbers addition to perform:

293 + 290 + 313 + 345

### Method used below: column adding, from right to left (traditional).

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

#### The ones digits line up in the first column from the right.

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

#### And so on...

## Add column by column; start from the column on the right.

### Add the digits in the ones column:

#### 3 + 0 + 3 + 5 = 11

#### How did we add the digits? Explanation below.

#### Group the ones together in order to make tens:

#### 3 + 0 + 3 + 5 =

#### 3 + 3 + 5 =

#### 6 + 5 =

#### 6 + 5 =

#### 6 + 4 + 1 =

#### 6 + 4 + 1 =

#### 10 + 1 =

#### 11

#### Change the order in which the numbers are added, the sum stays the same.

Break some number(s) into component parts, the sum stays the same.

#### The sum is a two-digit number: 11.

#### 1 is the ones digit.

Write it down at the base of 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.

### Add the digits in the tens column:

#### 9 + 9 + 1 + 4 + 1 = 24

#### How did we add the digits? Explanation below.

#### Group the ones together in order to make tens:

#### 9 + 9 + 1 + 4 + 1 =

#### 9 + 9 + 1 + 4 + 1 =

#### (9 + 1) + (9 + 1) + 4 =

#### 10 + 10 + 4 =

#### 10 + 10 + 4 =

#### 20 + 4 =

#### 24

#### The sum is a two-digit number: 24.

#### 4 is the tens digit.

Write it down at the base of the tens column.

#### 2 is the hundreds digit.

Carry it over to the hundreds column.

Write the digit above that column.

Add it with the rest of the digits in that column.

### Add the digits in the hundreds column:

#### 2 + 2 + 3 + 3 + 2 = 12

#### How did we add the digits? Explanation below.

#### Group the ones together in order to make tens:

#### 2 + 2 + 3 + 3 + 2 =

#### 2 + 2 + 3 + 3 + 2 =

#### 10 + 2 =

#### 12

#### The sum is a two-digit number: 12.

#### 2 is the hundreds digit.

Write it down at the base of the hundreds column.

#### 1 is the thousands digit.

Write it down at the base, next to the hundreds digit.

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

### The numbers addition to perform:

48 + 85

#### Method used below: column adding, from right to left (traditional)

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

#### The ones digits line up in the first column from the right.

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

### Add column by column; start from the column on the right

### Add the digits in the ones column:

#### 8 + 5 = 13

#### How did we add the digits? Explanation below.

#### Group the ones together in order to make tens:

#### 8 + 5 =

#### break into component parts: 8 + 5 =

#### 8 + 2 + 3 =

#### group by 2: 8 + 2 + 3 =

#### 10 + 3 =

#### 13

#### Change the order in which the numbers are added, the sum stays the same.

Break some number(s) into component parts, the sum stays the same.

#### The sum is a two-digit number: 13.

#### 3 is the ones digit.

Write it down at the base of the ones column.

#### 1 is the tens digit.

Add it with the rest of the digits in that column.

### Add the digits in the tens column:

#### 4 + 8 + 1 = 13

#### How did we add the digits? Explanation below.

#### Group the ones together in order to make tens:

#### 4 + 8 + 1 =

#### add marked digits: 4 + 8 + 1 =

#### (4 + 1) + 8 =

#### 5 + 8 =

#### break into component parts: 5 + 8 =

#### 2 + 3 + 8 =

#### group by 2: 2 + 3 + 8 =

#### (2 + 8) + 3 =

#### 10 + 3 =

#### 13

#### Change the order in which the numbers are added, the sum stays the same.

Break some number(s) into component parts, the sum stays the same.

#### The sum is a two-digit number: 13.

#### 3 is the tens digit.

Write it down at the base of 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.

### Answer:

48 + 85 = 133
