The variable values are right now located in the following registers Variable Register SO S] s2 Using ONLY "add" instruction, write a piece of MIPS assembly code that performs the following computation a = b +65 + c Hint 1: use the fact that 65=64+1. The number 64 is a power of 2 and that should hint you how to implement things efficiently. Hint 2: you might find MIPS register $zero useful. This register always contains the value 0 and can be used for example to copy the value from one register to another with only "add" instruction
