It's that time in my childrens' lives where they need to practice their basic math facts under a time limit. To help them, I created a simple Microsoft Small Basic program. You can view my code at http://smallbasic.com/program/?FHD214, or if you have Small Basic you can import my code with ID FHD214 and run the program. This program features the following:

• The user can choose from addition, subtraction, multiplication, or division problems.
• You can change the number of seconds that users are allowed to try to answer math problems.
• You can change the math problems' upper limits as users get more proficient.
• You can independently change the math problem types' difficulties. For example, for younger users you can make the multiplication and division problems eaiser than the addition and subtraction problems.  

Enjoy!
