Convince Excel to Treat a - as a Minus Sign in calculations and not a Negative

I understand why Excel is doing this as per this document, but I want to change the calculation order to not be a negative as I want it treated as an operator i.e. a minus.


2/4-3+9*6 = 51.5 according to Excel and Google treated as (2/4)-3+9*6 I think.

I however want it to calculate like this:

Division First = 2-3+9*6
Multiplication Second = 2-3+54
Addition Third = 2-57
Subtraction Last = -55

Any way I can change this behaviour with a custom function or indeed something else?

First, 2 divided by four is not 2. It is 0.5. Do you have this formula written correctly?

If you want the operations to occur in that fashion, utilize parentheses.

Also, as a point of clarification, the link your provided is not specific to Excel. In math, the order of operations is always handled using the PEDMAS rule: Parenthesis, Exponents, Division/Multiplication, Addition/Subtraction.

Sorry my mistake:

Division First = 0.5-3+9*6
Multiplication Second = 0.5-3+54
Addition Third = 0.5-57
Subtraction Last = -56.5

Yes I could be using brackets but I was hoping not to have to. Perhaps it is easier to show you the spreadsheet. Macros are in there for the custom formula.problem.xlsm

Sorry Shaun, I replied to your first comment and then saw the second. Yes I know it is following BODMAS (as we called it in my school days) but it is the minus sign that is being handled against my wishes and interpreted as a negative number i.e. negative 3 (0-3) not x-3=y.

It may not be doing what you want, but it is doing what it is supposed to, as written. Another way of writing that formula, per math rules, would be:

((2/4) - 3) + (9 * 6)

If you want both the 3 and 9 * 6 subtracted from the first part, you would either need to use brackets or distribute the minus sign:

2/4 - (3 + (9 * 6))   or (2/4) - 3 - (9 * 6)
