No, not necessarily. In theory you can assign different names to variables, and it doesn't always follow that they are alphabetical. So a divided by b could be x or t or n or any letter you like. Equally, you could use different letters in the initial calculation resulting in c, so x divided by y could be c. Having said that, letters used are commonly used in sequence, so a divided by b = c would be common. Having a, b and c together or x, y and z together is common. In certain situations though, certain letters are given special designations as in the famous E = mc² equation.
