i need to write a short response:

a number is divided by 2, then is subtracted from the result.
what operations are needed to return to the original number?

im not sure how to answer this
can you help[

Certainly! To return to the original number after dividing it by 2 and then subtracting the result, you would need to reverse those operations.

Let's say the original number is "N." To go back to N, you would first add back the result of dividing N by 2. This can be represented as:

N/2 + (N/2 - N)

Simplifying that expression:

N/2 + N/2 - N

Combining like terms:

2N/2 - N

Finally, simplifying further:

N - N

So, the answer is 0. To return to the original number, you would need to perform the operations of division and subtraction, and the resulting value would be 0.

Hope this clarifies things! Let me know if you have any further questions.
