Question

Using the digits 0 to 9 at most one time each, fill in the boxes to generate equivalent numerical expressions.

Answer 1

To generate equivalent numerical expressions using the digits 0 to 9 at most one time each, follow these steps: choose two digits, swap them, subtract the smaller from the larger, and put the result in the third box.

Step-by-step explanation:

To generate equivalent numerical expressions using the digits 0 to 9 at most one time each, you can use the following steps:

1. Choose any two digits from 0 to 9 and place them in the two boxes of the expression.
2. Swap the digits in the boxes and subtract the smaller digit from the larger digit.
3. Put the result in the third box to complete the expression.

For example, if you choose the digits 7 and 4, and place them in the first two boxes, you can swap them to get 4 and 7. Subtracting the smaller digit from the larger digit gives you 7 - 4 = 3, which can be placed in the third box to create the expression 4 - 7 = 3.
