Question: how do i do this write lmc programs to complete...

Question details

How do I do this:

Write LMC programs to complete the following task. Write the solutions using Numeric code and using Mnemonics and Labels.

Write two programs, one to Add two numbers and another Subtract two numbers.

How do I write this out in an LMC editor? I am new to this so I don't understand how to do this. As I keep getting "Duplicate Logic Error" every time I try to enter the below code:

Program to add two numbers

INP 
STA first 
INP 
ADD first 
OUT 
HLT 

Program to subtract two numbers -

INP 
STA first 
INP 
SUB first  
OUT 
HLT 

Do I need to enter the below image out in the LMC editor to solve the question above?

The program begins with the selection of 6 programs to choose. 0 Countdown * 1 Square . 2 Fibonacci sequence 3 Triangular numbers * 4 Decimal to binary converter . 5 Binary to decimal converter [01-COUNTDOWN [11-SQUARE -[2]-FIBONACCI [3]-TRIANGULAR NUMBERS [4]-DEC TO BIN [51-BIN TO DEC START IN BRZ SUB BRZ SUB BRZ SUB BRZ SUB BRZ SUB BRZ user commands COUNTDOWN #0 ENTER [0] FOR COUNTDOWN one SQUARE #1 ENTER [1] FOR SQUARE one FIBONACCI #2 ENTER [2] FOR TRIANGULAR NUMBERS one TRIANG #3 ENTER [3] FOR FIBONACCI SEQUENCE one DECTOBIN #4 ENTER [4] FOR DECIMAL TO BINARY one BINTODEC #5 ENTER [5] FOR BINARY TO DECIMAL
