1. **State the problem:** We need to subtract 172 from 5924, i.e., calculate $5924 - 172$. 2. **Set up the subtraction:** Write the numbers in column form aligning digits by place value: \begin{array}{r} 5924 \\ - 172 \\ \hline \end{array} 3. **Subtract the units place:** $4 - 2 = 2$. 4. **Subtract the tens place:** $2 - 7$ is not possible without borrowing. Borrow 1 from the hundreds place (9 becomes 8), so tens place becomes $12 - 7 = 5$. 5. **Subtract the hundreds place:** Now $8 - 1 = 7$. 6. **Subtract the thousands place:** $5 - 0 = 5$ (since there is no digit in the thousands place of 172). 7. **Write the result:** The difference is $5752$. **Final answer:** $$5924 - 172 = 5752$$
