ADD and SUBTRACT whole numbers and DECIMALS

Objectives: At the end of 45 -minute period , the students are able to: a. add and subtract b. relate addition and subtraction in real life c. perform the indicated operation

To Add decimal numbers 1. Put the numbers in a vertical column, aligning the decimal points. 2. Add each column of digits, starting on the right and working left. If the sum of a column is more than ten, “carry “digit to the next column on the left. 3. Place the decimal point in the answer directly below the decimal points in the terms.

Examples: 0. 468 213 +0. 220 128 0. 326 +0. 138

Examples: 0. 468 213 +0. 220 128 0. 688341 0. 326 +0. 138 0. 464

To Subtract decimal numbers 1. Put the numbers in a vertical column, aligning the decimal points. 2. Subtract each column, starting on the right and working left, if the digit being subtracted in a column is larger than the digit above it “barrow” a digit from the next column to the left. 3. Place the decimal point in the answer directly below the decimal points in the terms. Example: 48. 18 17. 29 0. 4 - 2. 02 -4. 11 - 0. 282
