I'm working in assembly using nasm, and need to create a program that performs simple calculations. The prompt is below:

Write a program that contains 4 procedures:

ADD

SUBTRACT

MULTIPLY

DIVIDE

Read expressions from the user, such as:

1 + 2

4 - 3

2 * 3

4 / 2

.

Execute every expression by calling the proper procedure.

The end of user input is a period: .

The output for the above code should be:

1 + 2 = 3

4 - 3 = 1

2 * 3 = 6

4 / 2 = 2
