main:
        li $2,4              # System call code for print string
        la $4,Input          # Argument string as Input
        syscall              # Print the string

        li $2,5              # System call code to read int input
        syscall              # Read it
        move $16,$2          # move the num entered into $16

	   li $2,5              # System call code to read int input
        syscall              # Read it
        move $17,$2          # move the num entered into $16

        add  $18, $16, $17
Answer:
        li $2,4              # System call code for print string
        la $4,Output         # Argument string as Input
        syscall              # Print the string

        li $2,1              # system call code for print int
        move $4,$18          # return_value as argument
        syscall

        
Exit:   li $2,10             # System call code for exit
        syscall              # exit
