Hello all, I’m quite new to this forum,

so forgive me if I break a few rules unknowingly

anyways, I have a question : how would one subtract a list of numbers in

a row?

for example,

a = 1

b = 7

c = 3

d = 5

e = 9

I want to subtract all the numbers in this format :

a - b - c - d - e = ?

(keep in mind that there won’t always be 5 numbers, and the numbers

won’t always be constant)

thanks in advance
