EDUCATIONAL MATH










This program explores fractals (Mandelbrot Set) in a powerful way. It even lets you create bitmaps which you can print with common windows tools. Once you execute the program, you can left click with the mouse to magnify the picture 10X or right click to step back 10X. There are also menu options.

This calculator displays random prime factor trees. To calculate the prime factors that make up a composite number, you can break up the composite number into smaller composite numbers and primes. This calculator illustrates how to do that.

Prime Factorization Tree



This calculator breaks up a composite number every possible way it can be broken up using two unique factors. It illustrates that all the possible ways are found by just combining the prime factors in different combinations.

Breaking Up Composite Numbers



This calculator computes every two numbers that can be multiplied together to produce the number you enter. Any one of these numbers will divide evenly into the number you enter and thus they are divisors. When you supply two numbers, it calculates the divisors for both numbers and highlights the greatest divisor in common in yellow. This is called the Greatest Common Divisor or GCD. Common Divisor Calculator



This calculator reduces a regular fraction into its simplest form. Enter the numerator first and then the denominator. It will display the reduced fraction. If the fraction is improper, it will also display the fraction in mixed form.

Fraction Reduction Calculator



This calculator converts a mixed fraction into a regular fraction. Just type in the integer, numerator, and denominator in that order. The answer is displayed in green.

Converting a Mixed Fraction



This calculator shows you how to add two fractions. It assumes you know how to find the Greatest Common Divisor of two numbers. If you do not know how to find the GCD, please review the calculators above.

Adding Two Fractions



This is a cool web site that shows how to break up numbers into their prime factors to compute the GCF (GCD) and LCM (LCD).

Prime Factorization Tree Applet



This is just a cool web site that shows how to prove Pythagoreans Theorem. A square is made from each side of the right triangle thus you have three squares with the areas A squared, B squared, and C squared. The squares for B and C can be broken up into pieces and moved to exactly fit square A. This proves that A squared = B squared + C squared!

Complex Maze

This free download is a complex maze that children as young as ten years old have solved. You can get from any point in the maze to any other point in the maze by one and only one path. Thus there is only one path from the beginning to the end. All you need to do is open this bit map and print it. Alternatively, you can download it as a zip file. If you open the bmp file in Paint, there is a way to expose the solution. (Public Domain)
