<reasoning>

Calculate column subtraction for problems (9) to (13)

\[

$$\begin{aligned} (9) \quad &235 - 17 = 218 \\ (10) \quad &235 - 29 = 206 \\ (11) \quad &235 - 53 = 182 \\ (12) \quad &235 - 63 = 172 \\ (13) \quad &235 - 83 = 152 \end{aligned}$$

\]

Calculate column subtraction for problems (14) to (18)

\[

$$\begin{aligned} (14) \quad &335 - 18 = 317 \\ (15) \quad &335 - 54 = 281 \\ (16) \quad &335 - 27 = 308 \\ (17) \quad &335 - 62 = 273 \\ (18) \quad &335 - 72 = 263 \end{aligned}$$
