Arithmetic Operations
Arithmetic instructions allow you to perform various arithmetic function of data. "ADD" and "SUB" work the same way as "MOV" instructions do in that it subtracts whatever is in the source register from the destination register and stores it in the destination register. The "MUL" and "DIV" instructions are a bit more complicated and they are not used as intensively as the "ADD" or "SUB" since they are slow.
