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

$\left. \begin{array} { r } { 12.35 } \\ { + 1.08 } \\ \hline \end{array} \right.$

$\left. \begin{array} { r } { 12.35 } \\ { + \quad 1.08 } \\ \hline 13.43 \end{array} \right.$

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
