Understand math and numbers better, whether it be for school or any other purpose. This app can help you with many numerical tasks including:
• Factoring
• Prime Factorization
• Greatest common divisor
• Finding prime numbers
• Conversion of a decimal to a fraction
• Simplification of Fractions
• Fraction Arithmetic
• Random Number Generation
You can expect speed, some of the fastest known algorithms are used in the calculations and all of the operations are computed on your physical device. This takes off the time that would otherwise be used to communicate with servers through the internet. The one exception to this is the nth prime page which contacts a server to be able to quickly give you up to nearly the 10 trillionth prime number in just seconds.
