The document provides instructions for performing basic arithmetic operations with decimals, including adding, subtracting, ordering, and evaluating expressions. It explains how to line up the decimals when adding or subtracting, and describes the steps to take such as borrowing when subtracting. It also demonstrates how to order a list of decimals from least to greatest and evaluate expressions by performing the indicated operations.
3. Adding Decimals Start with the problem: 706 + 3.02 Re-write the problem and line up the decimals. Remember whole numbers have a decimal to the right of the ones digit. Add any additional zeros after the decimal point. 706.00 + 3.02 -------
4. Adding Decimals Start with the problem: 706 + 3.02 Re-write the problem and line up the decimals. Remember whole numbers have a decimal to the right of the ones digit. Add any additional zeros after the decimal point. 706.00 + 3.02 ------- 709.02 Add the digits starting at the right working to the left. The decimal in the answer must line up with the decimals you are adding.
6. Subtracting Decimals Start with the problem: 702 - 3.02 Re-write the problem and line up the decimals. Remember whole numbers have a decimal to the right of the ones digit. Add any additional zeros after the decimal point. 702.00 - 3.02 -------
7. Subtracting Decimals 1 702.00 - 3.02 ------- Remember to borrow from the number CLOSEST to the zero you are working with!
8. Subtracting Decimals 1 702.00 - 3.02 ------- Remember to borrow from the number CLOSEST to the zero you are working with! 1
9. Subtracting Decimals 1 9 702.00 - 3.02 ------- Remember to borrow from the number CLOSEST to the zero you are working with! 1

11. Subtracting Decimals 1 9 702.00 - 3.02 ------- .98 Remember to borrow from the number CLOSEST to the zero you are working with! 1 1
12. Subtracting Decimals 1 9 702.00 - 3.02 ------- .98 Remember to borrow from the number CLOSEST to the zero you are working with! 1 1
13. Subtracting Decimals 6 1 9 702.00 - 3.02 ------- .98 Remember to borrow from the number CLOSEST to the zero you are working with! 1 1 1
14. Subtracting Decimals 691 9 702.00 - 3.02 ------- 8.98 Remember to borrow from the number CLOSEST to the zero you are working with! 1 1 1 1
15. Subtracting Decimals 691 9 702.00 - 3.02 ------- 98.98 Remember to borrow from the number CLOSEST to the zero you are working with! 1 1 1 1
16. Subtracting Decimals 691 9 702.00 - 3.02 ------- 698.98 Remember to borrow from the number CLOSEST to the zero you are working with! 1 1 1 1
