An Excel Formula Question

I have taken over a new position at work. This person who I replaced had
created a worksheet that calculates revenue recovery for specific units of
time then also calculates the aggregate revenue recovery over a period of
multiples of these specific units of time. Below is an example of this
formula for the individual unit of time and one for the average over multiple
units of time.

individual =1-(+I38/C37)
multiple =1-(SUM(I38:AK38)/SUM(C37:AE37))

My question is what does the 1- at the beinning of each of these formulas
do? Is it a some type of function like the 3 (counts) or the 9 (sums) do in
the below examples? If so what is its function?

=subtotal(3,a2:j2)
=subtotal(9,a2:j2)

Any help would be GREATLY Appreciated.

Thank you,

The first formula subtracts I38/C37 from 1 (note that the + is
superfluous)

The second formula subtracts SUM(I38:AK38)/SUM(C37:AE37) from 1.
 
JE,

Thank you for your quick reply. However I am still confused. is the 1 a
function of somekind or is it simply just a random number? In other words
what is the purpose of subtracting the value I38/C37 from 1?
 
It is a number, but I doubt it is random.

Is the cell formatted as percentage? I am thinking that the guy was able to
calculate a percentage for a particular case, but he wanted to know the 'not
case', so he subtracted it from 1 (1 - 40% gives 60%).
 
Bob,

Yes, the cell is formatted as a percentage. I have tried changing the 1 to
a different number and when I do the result becomes some astranomical number
that makes no sense.
 
Ah HA! Bob, I think I understand it now. If I understand your reply
correctly 1 simply represents 100% of what ever the beginning number is. Am
I correct?
 
Exactly right.
