Explanation: You cannot perform addition on three operands simultaneously because the third operand is where the result is stored. 4. The instruction, Add R1,R2,R3 in RTN is _______ .
A. R3=R1+R2+R3
B. R3<-[R1]+[R2]+[R3]
C. R3=[R1]+[R2]
D. R3<-[R1]+[R2]
Answer:D

A. R3=R1+R2+R3 B. R3<-[R1]+[R2]+[R3] C. R3=[R1]+[R2] D. R3<-[R1]+[R2]
Explanation: In RTN the first operand is the destination and the second operand is the source. [/expand]
