# Wish: Multiple subtraction

(Aris Nikolopoulos) #1

Hi,
Just a small thing: it would be nice to have subtraction with multiple inputs just like addition.

You would ask me: and what will be subtracted from what? To me it seems pretty straightforward: all inputs are subtracted from the first one.
It would cover the uncanny valley between using a single operator and having to use expression for simple operations…
thanks!

A-B-C-D-E… = A -(B+C+D+E+…)

Doing something is one thing, doing something fast is another:
Even in the example I gave, it was done with 2 components. I’m just saying it would be faster and more efficient with one component.
edit: I just noticed the 666. hahahahaha 1998 must have been your year!

Too late, it’s already possible in Rhino6. Subtraction and Multiplication support multiple inputs. (It could be this is 6.1 only, I don’t exactly remember when this was added). I did not do the same for division, because that was just too weird…

a+b+c+...+z
a-b-c-...-z
a \cdot b \cdot c \cdot ... \cdot z

All fine, but

\frac{a}{\frac{b}{\frac{c}{...}}}

is probably not useful.

that’s it. I’m going to buy rhino 6…
(I’m currently using a license which technically does not belong to me, so I can’t upgrade. I have to buy it whole, but I don’t want to stay behind)
