Add Numbers: 163 + 334 + 448. Calculate the Sum and Learn How To Do the Addition, Column Adding Method. Online Calculator

The numbers addition to perform:
163 + 334 + 448

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...


 163
 334
+ 448
?

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

Add the digits in the ones column:

3 + 4 + 8 = 15

How did we add the digits? Explanation below.

Group the ones together in order to make tens:

3 + 4 + 8 =

3 + 4 + 8 =

7 + 8 =

7 + 8 =

2 + 5 + 8 =

2 + 5 + 8 =

(2 + 8) + 5 =

10 + 5 =

15


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: 15.

5 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:

6 + 3 + 4 + 1 = 14

How did we add the digits? Explanation below.

Group the ones together in order to make tens:

6 + 3 + 4 + 1 =

6 + 3 + 4 + 1 =

(6 + 4) + 3 + 1 =

10 + 3 + 1 =

10 + 3 + 1 =

10 + 4 =

14



The sum is a two-digit number: 14.

4 is the tens digit.
Write it down at the base of the tens column.

1 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:

1 + 3 + 4 + 1 = 9

9 is the hundreds digit.
Write it down at the base of the hundreds column.

Final answer:

163 + 334 + 448 = 945

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.
    •  48
      + 85
      ?
  • 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? Group the ones together in order to make tens:
    • 8 + 5 = (break 5 into component parts 2 and 3) 8 + 5 = 8 + 2 + 3 = (add 8 and 2 first) (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 - 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:
    • 4 + 8 + 1 = 13
    • How did we add the digits? Group the ones together in order to make tens:
    • 4 + 8 + 1 = 4 + 9 = 3 + 1 + 9 = 3 + (1 + 9) = 3 + 10 = 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
