Decimal Addition With 3 Numbers

Addition of three decimals is similar to addition of two decimals.

The decimals are first apgned vertically so that digits of same place value are added.

Zeros are added to the right of decimal numbers where ever necessary so that all numbers have the same number of digits after the decimal point.

Add 67.07 + 13.41 + 7.30

Solution

Step 1:

The decimals are apgned vertically above one another as shown.

Step 2:

We begin at the rightmost column 7 + 1 + 0 = 8; moving left 0 + 4 + 3 = 7; then

7 + 3 + 7 = 17. We bring down 7 and carry 1 to next column where 6 + 1 + 1 = 8.

Step 3:

We bring down 8 and get the final sum as shown.

Add 83.19 + 33.41 + 19.62

Solution

Step 1:

The decimals are apgned vertically above one another as shown.

Step 2:

We begin at the rightmost column 9 + 1 + 2 = 12; We bring down 2 and carry 1 to next column; moving left 1 + 4 + 6 + 1 = 12; We bring down 2 and carry 1 to next column; next 3 + 3 + 9 + 1 = 16. We bring down 6 and carry 1 to next column where 8 + 3 + 1 + 1 = 13.

Step 3:

We bring down 13 and get the final sum as shown.
