We can draw a number line and count.
\begin{tikzpicture}[x=0.72cm,y=0.72cm,>=Stealth]
% Number line
\draw[->, line width=0.7pt] (-5.65,0) -- (10.65,0);
% Tick marks and labels
\foreach \x in {-5,-4,...,10} {
\draw[line width=0.65pt] (\x,0.12) -- (\x,-0.12);
\node[below=3pt, font=\scriptsize] at (\x,0) {$\x$};
}
% Hop from 0 to 5
\draw[->, line width=1.1pt]
(0,0.18) .. controls (1.2,0.68) and (3.8,0.68) .. (5,0.18);
\node[font=\small\bfseries] at (2.5,0.80) {$+5$};
% Hop backward 7 from 5 to -2
\draw[->, line width=1.1pt]
(5,0.28) .. controls (3.3,1.92) and (-0.3,1.92) .. (-2,0.28);
\node[font=\small\bfseries] at (1.5,1.92) {$-7$};
% Emphasize the landing points
\fill (0,0) circle (1.5pt);
\fill (5,0) circle (1.5pt);
\fill (-2,0) circle (1.5pt);
\end{tikzpicture}
We see that counting forward $5$ and backward $7$ makes us land at $-2$.
Final answer:
-2
