For WA, is it okay to set variables equal to specific answers to reference them later

For example, if I need to calculate 5V

Can I write: 5V = Ax+5 - Pax+5

then say Ax+5 = 0.243568 = x

P = 0.004236 = y

ax+5 = 12.32456 = z

then 5V = x - y * z

then whenever I have to use any of those in subsequent parts for this question, I can just reference the variables I defined.

Do you think that would be okay strategy to use?

Some of the numbers on the WA have so many decimals and I don't want to keep re writing them

I think this would be okay if you're explicit in your approach. I could be wrong though

Conceptually, it's a good idea, but if you're going to do this, I'd advise against using "x", "y" or "n" - those appear too often in the general notation of the exam that it may be difficult for the grader to ascertain exactly what you're trying to do.

I could see the point if you had a complex expression without a specific symbol associated to separate from your equation, but why would you do this in your example? What is the point of saying P = y and use y when you can just use P?

I kind of meant it the way you described it
