C = (x/y) - (z/w)

A + B = C

A = x/w

B = ??

B = C - A

B = [(x/y)-(z/w)] - x/w

It's Maths, short for mathematics. We are not in the USA.

B = (wx/y) - z - x

That's wrong Harry... if you multiply out by w you need to do it on both sides of the equation...

B = x/y - (x+z)/w

But is there something more to this as it's an easy bit of algebra...

Yep I agree. It's not help with maths you need, just your spelling.

Tssk.

Basically I am doing a variance analysis with 3 variables
Moves
Fixed Costs
Variable Costs

and I need to 'bridge' the cost per move kpi

here is the spreadsheet and I need to 'prove' the delta at the bottom with just saying its what is left over
