Add multiple values to one value

Hi, I am begginer and I am working on my project. I want to add three values to one value but I dont know how. Some of the values have to be multiplied. Here is the example:

X = 3600Y + 60Z + C

how would you do that? Will this work?

Post your current program, using code tags.

X = 3600Y + 60Z + C

Will this work?

Did you try to see if it works?

I have just made it working, sorry for stupid question. It worked as I wrote in the example.
