Subtract: \( 33,115-21,574 \)

To solve \( 33,115 - 21,574 \), start by aligning the numbers vertically: ``` 33,115 - 21,574 _________ ``` Now, subtract starting from the rightmost column: 1. In the units column: \( 5 - 4 = 1 \) 2. In the tens column: \( 1 - 7 \) requires borrowing, so it becomes \( 11 - 7 = 4 \) 3. In the hundreds column: after borrowing, \( 0 - 5 \) again requires borrowing, changing it to \( 10 - 5 = 5 \) 4. In the thousands column: \( 2 - 1 = 1 \) 5. In the ten-thousands column: \( 3 - 2 = 1 \) Putting it all together, we find: ``` 33,115 - 21,574 _________ 11,541 ``` So, \( 33,115 - 21,574 = 11,541 \).
