Continuing the discussion from How to remove Items from my customer receipt:
Hey @JTRTech did you ever get a reply to this question? The /20 has me puzzled as well. I see that “Q” also quoted in his posts on various occasions. This was the best I could find:
Anyway interested to know the meaning, thanks.
My query was to what it was ie tip/tax.
/20 is obviously decide by 20 or 5% 
It has sort of got me stuffed as I note “Q” has it in his “Accounts Type” Tile format and I have been staring past it for weeks until now. So we divide all Totals Sales by 20 to give us?..
Here is my Tile:
Here is the syntax (last bit towards the end in brackets):
Sales: [=F(-1*(TN('{ACCOUNT TOTAL:Sales}')+TN('{ACCOUNT TOTAL:Sales T1}')+TN('{ACCOUNT TOTAL:Sales T2}')),'0.00')] ([=F(-1*(TN('{ACCOUNT TOTAL:Sales}')+TN('{ACCOUNT TOTAL:Sales T1}')+TN('{ACCOUNT TOTAL:Sales T2}'))/20,'0.00')])
It has to be something very simple that I am looking too hard for 
I asked out of curiosity on that topic, it was on printer template so presumed it was showing some form of tax as a calculation rather than using the tax setup in samba.
Given the worldwide use of samba it would be any number of things.
I beleive Qmckay is UK based and the only tax we have here is VAT at 20% so not sure what 5% (/20) would represent…
Surely you dont need to copy everything 
if it means nothing to you leave it out LOL
Yep - leaving it out was my next step. If you search the forum it has been used quite a bit in report templates and it not really Qmackay’s style to hard code a tax rule? Just thought it may have been something important 
so your thinking is the same as mine - its gone, gone…
Its something custom for him probably a % he keeps for something.
LOL, yes it is a hard-coded currency conversion. You can remove it.
