Sum the first three variables and store the result in the fourth variable. add Integer addition The add instruction adds together its two operands, storing the result in its second operand. Note, whereas both operands may be registers, at most one operand may be a memory location. Syntax add , add , add , add , add , Any 8-, 16-, 32 or 64-bit immediate Examples add $10, %eax - EAX is set to EAX + 10 addb $10, (%eax) add 10 to the single byte stored at memory address stored in EAX
