QUESTION 3:
Write and run LMC code that would input 2 numbers (Let say, A and B) and then you will add OR multiply the numbers dependin on your input !sinal" (# or 2)$ %& you input a '#, LMC will A the 2 numbers (A*B) but i& you input a '2, LMC will M+L%-L. the 2 numbers (A/B)$ Run in the simulator and chec0 your codes$ hen you need to ma0e a 1ideo to eplain your answer$
