Understanding Operator Promotion
Implicit conversions are also associated with operator promotion, which is the automatic conversion of an operator from one type to another. When you do basic arithmetic operations on two variables, they are converted to the same type before doing the math. For example, if you add a byte variable to an int variable, the byte variable is promoted to an integer before it is added.
A numeric variable smaller than an int is promoted to an int. The order of promotion after an int is as follows:
