Worksheet Worksheet 2

1.
Calculate \(19 - 45\) using a number line.
2.
Calculate \(-28 - 46\) using a number line.
3.
Calculate \(-15 + 73\) using a number line.
4.
Practice your mental arithmetic by performing the following calculations without drawing a number line (though you may certainly visualize one).
\begin{equation*} \begin{aligned} 33 - 57 \amp = \\ -38 + 19 \amp = \\ -32 - 29 \amp = \\ -42 + 70 \amp = \\ -43 + 37 \amp = \\ 72 - 34 \amp = \\ 38 - 14 \amp = \\ -52 + 31 \amp = \\ -22 + 49 \amp = \\ -18 - 35 \amp = \\ 28 - 63 \amp = \\ -24 + 15 \amp = \end{aligned} \end{equation*}
