Consider a computer that has a number of registers such that the three registers R0 = 1500, R1 = 4500, and R2 = 1000. Show the effective address of memory and the registers’ contents in each of the following instructions (assume that all numbers are decimal).

(a) ADD (R0)+, R2
(b) SUBTRACT - (R1), R2
(c) MOVE 500(R0), R2
(d) LOAD #5000, R2
(e) STORE R0, 100(R2)

**I can get the register contents but I don't know how to get the effective address??
