# Simple maths help. watch

1. This may seem easy to you guys but I dont have a particularly strong maths background so it confuses me a little bit.

Lets say, A = B x C / D

How do I make each of the letters the subject of the formula, like what do I have to do?

To make B or C the subject: multiply both sides by D. Then divide both sides by either B or C (depends which one you want to make the subject.

Make D the subject: multiply both sides by D. Divide both sides by A

A = B x C / D
To make B the subject, you take eeverything to one side, apart from B
Ax D/C = B
C as the subject
A/B x D = C

Ax D/C = B
C as the subject
A/B x D = C
What about making D the subject?

What about making D the subject?
D = (B x C) /A
6. (Original post by qwerty123A)
What about making D the subject?
A = B x C / D
AxD=BxC
D=B/A x C/A
7. (Original post by Rickstahhh)
D = B x C /A
both b and c over A, just to clarify
8. I get it now, thanks guys
