3-35.

Find the following sums or differences. Homework Help ✎

  1. 12.35 + 1.08

  • Align the terms at their decimal points.

  • Add each column, starting at the right. Since 5 + 8 > 10, carry a 1 to the next column.

  • 13.43

  1. 8.02 − 0. 64

    Set up the problem by aligning the decimal points. Unlike in part (a), you will do subtraction for each column.

    Notice that 2 < 4, so you will need to ''borrow'' from the columns to the left.

  2. 568.38 − 134.21

    Use parts (a) and (b) for help.

  3. 0.29 + 0.92

    Follow the steps from part (a). Remember that since 9 + 2 > 10, you will need to carry a 1 to the next column
