Mental Math Drills

On the right your will see all of the flashcard-like drills relating to mental math.

To begin a drill, click on the word start in front of the drill you wish to use.

As each question appears, think of your answer and then click on the "show answer" button to see the correct answer. The same button now reads, "Next Question." Left mouse click on that button and a new question will appear. You will never be required to type in your answer. Just think your answer and click the button to see the correct answer.

Use these drills just as you would use normal flashcards. If your answer is wrong, stop to think about the correct answer for that problem.

When you are ready to stop, click on the "Stop Sign." The duration and rate in which you progressed will be displayed on the screen. Practice just 5 minutes a day and watch how quickly your speed and accuracy improves.

Many of the more advanced drills require that you use a special strategy/trick. Learn the trick with the rightmost link before attempting to start one of these drills. Do not use conventional strategies on these drills.
