Ok. Look at my user page, there’s a s3ction on editing which includes links to documentation for some of the functions. Basically, every function is wrapped in two {} curly bracket sets and every parameter is wrapped in three. It gets quite confusing when they’re all crammed together, just count and pair them off.

{{#vardefine:c|{{#expr:{{#var:c}}+1}}}

Starting from the inside
 * use the #var function to get the variable c
 * use the #expr function to return the value of c + 1
 * use the #vardefine function to redefine the variable c

It really is a case of learning by trying, copying what others have done and asking questions ... there are a lot of people on here who will be happy to help you.
