n an attempt to do a three-digit subtraction, Yuan writes the following. dentify what she is doing incorrectly, and determine how you will help correct her error. A. Yuan forgot to carry the 1s. B. Yuan switched the order of the minuend and the subtrahend. C. Yuan made only a minor arithmetic error. D. Yuan is subtracting up with some of the digits. Dorrect answer below. Use the Show Work feature to provide related calculations and additional reasoning to suppo D.

Oops! It looks like Yuan is trying to subtract up instead of down, which is a common pitfall in subtraction. When subtracting, we generally start from the rightmost digit and move left, borrowing if necessary. To help Yuan, we can break down the subtraction step by step, showing her how to line up the numbers properly and handle borrowing if the digit on top is smaller than the one below. Here’s how we could demonstrate: If Yuan is trying to subtract 432 from 759, we would line it up: ``` 759 - 432 ------ ``` Starting from the right, 9 - 2 = 7, then 5 - 3 = 2, and finally 7 - 4 = 3. So the answer is 327. By showing her these steps, we can help correct the error and strengthen her subtraction skills!
