Addition of Apgned Decimals

The decimals are apgned so that the digits of same place values are above and below each other. Such decimals are apgned decimals. It is necessary that the decimals are apgned before addition. Addition of apgned decimals is similar to addition of whole numbers.

Apgning the decimal numbers so that digits of same place values are pned up vertically one above the other

Adding zeros to the right of the decimal numbers where ever necessary.

So, at first the decimals are apgned so that the digits of same place values are above and below each other. Then zeros are added to the right of decimal numbers as required. We begin with the rightmost column and start adding the digits. Then we keep moving to the left till all columns are added.

Add 12.53 + 6.32

Solution

Step 1:

The decimals are apgned as shown.

Step 2:

We start with the right most column. Add 3 + 2 = 5; then moving to left column 5 + 3 = 8; again 2 + 6 = 8; next 1 + 0 = 1.

Step 3:

So the sum of the decimals is 18.85

Add 13.41 + 7.309

Solution

Step 1:

The decimals are apgned as shown. A zero is added to the right of 13.41 as the maximum number of decimal places is 3.

Step 2:

We start with the right most column. Add 0 + 9 = 9; then moving left 1 + 0 = 1; again 4 + 3 = 7; next 3 + 7 = 10 we bring down 0; carry 1 to next column. 1 + 1 = 2;

Step 3:

So the sum of the decimals is 20.719
