How to add a subract field in a word

[ATWR]

Hi guys

I'm setting up and invoice in word and have managed to figure out how to do
the 'sum above' formula and also work it out so it adds VAT it is set out
like below...

£100
£100
£100

Sub total: £300 (sum above)
VAT:???
Total: £352.50 (=B6*1.175)

The one thing i want it to work out for me is the VAT as a stand alone total
as we need to show this between the 2 values (sub total / total) so i thought
it would just be a matter of adding a subtraction formula in the cell i want
it then doing a eg. C6-C4 (total - subtotal) but i can't work out to do the
formula!

can anyone help - much appreciated if you can!!!! thanks can't find
subtraction anywheere!!!

Why not just (=B6*0.175)?

Your welcome.
FYI, to answer your first question.
=B8-B6
would give you the subtraction syntax you require.
Best of luck
