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*}
