can I create variable by mathematical operation

[Ketaki kate]

I am trying to do a automation which contains Two mathematicl operation. so first variable created with just fetching value of A field. Now I am creating second variable by fetching value of B and adding variable A. is it possible.

Finally, I will update the D field by just fetching value of C and subtracting (variable B+A) from it.

Hi Kate,

I stumbled across this searching for something similar, so I thought I would answer on the chance it helps someone else. 

I don't believe this will work for your use-case. The created variable can be created from math expressions but not used in subsequent math expressions as it is returned as a string and not a number type. 

You can combine the entire equation into a single call. I haven't tested it, but it will be something as shown below. 

For example

There is an automation action called "Create variable" which will evaluate an expression and set its result to a new variable.

It can work with smart values, so it should fit your use case.
