To subtract \(-18\) from \(17\), we follow the rule that subtracting a negative number is the same as adding its positive counterpart.
So, the expression \(17 - (-18)\) can be rewritten as:
\[ 17 + 18 \]
Now, we simply add \(17\) and \(18\):
\[ 17 + 18 = 35 \]
Thus, the result of \(17 - (-18)\) is \(35\).
