$A = 1000, B = 0.6$

$Y \times B = A ; (? \times 0.6 = 1000)$

Need to find $Y$ every time I change $A$ or $B$. How do i ask a calculator to do that (: ?

(I managed to reverse engineer a way from another answer by René Richter - which is)

$(1 / B) \times A$

Any other obvious ways to calculate this that I'm missing? Yes i know its probably pitiful, but a headache and silly math skills only get so far ...

Thx in advance. Thx in advance.

I'm not very sure what you are trying to accomplish here:

if $$Y = A/B $$

Then if you change B, simply divide it by your value of A to find Y.

Similarly if you change A, you would follow the same process.

  • yes that "$Y=A/B$" was "the alternative way to find $Y$" that i looking for. ...Just expanding my low level math, bit by bit. thank you. It definitely wouldn't have occurred to me. – helena4 Jun 30 '14 at 10:51
  • @helena4 no problem – Varun Iyer Jun 30 '14 at 10:54
  • @helena4 Note that this isn't just some method that happens to work, this is what division is for. The definition of $a/b$ is "what do I need to multiply $b$ by to get $a$". – Jack M Jun 30 '14 at 10:55

    @JackM ...Well thats what happens when you got a boring teacher. They tell you to jump and how high, but most of them forget to let us in on the "why the hell are we jumping?!" – helena4 Jun 30 '14 at 12:40
