Using the basic arithmetic operations, how quickly can YOU reach a total of 24 using the numbers on the four cards once each? This well designed java applet keeps a running score (requires a java-capable browser). Challenging and FUN!! If you get stuck, clicking on the "stop" button will display the correct solution.
The applet takes a moment to load... be patient; it's worth it!! [You can click "Cancel" on Chinese font download; this will not impact the game.]
Add, Subtract, Multiply, or Divide using this Java applet. Press "New Equation" to begin and press the button with the actual answer to the problem. [Source Code is provided.]
Much of math instruction today focuses on exploring, discovering,
collecting data, and working out real life problems. However there is still a place for number facts and being able to calculate "on the fly" can be advantageous. Automaths doesn't teach you how to get to an answer, but it does provide valuable practice for these automatic response skills. Choose from three levels:
Junior: Challenges your addition and subtraction skills
Middle: Will give you problems using addition, subtraction and multiplication.
Senior: Challenges your skills using all of the above and division too.
Can you do this page in ONE minute?
This program provides lots of practice with addition, subtraction, multiplication and
division problems and marks your work. You may specify highest number and whether to allow negative numbers or remainders (you'll need Explorer 3.0-Win95 or
Netscape 4.0). Be patient -- it will take a minute to load...
