Subtracting numbers

Subtracting numbers using LiveCode is a simple task. To demonstrate how to subtract one number from another, we will create a user interface that accepts two numbers, and when the equals sign is selected, the results will be displayed.

How to do it...

Follow the steps in this recipe to create an interface and LiveCode script that subtracts one number from another:

   • Height: 31

   • Location: 194, 53

   • Font: Courier

   • Text size: 18

   • Align text right

   • Name: fld_nbr2

   • Width: 88

   • Height: 31

   • Location: 194, 95

   • Font: Courier

   • Text size: 18
