Math Tools B vs Guess the Graph

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.

Graph Detective is an interactive educational app that helps students build intuition about mathematical functions by analyzing graphs instead of memorizing formulas. Players are shown a graph without its equation and are challenged to reconstruct the underlying function by adjusting parameters or entering expressions. As users experiment, the graph updates in real time, encouraging exploration and hypothesis testing. The app supports multiple difficulty levels: Easy: Explore quadratic and linear functions using sliders Medium: Enter full expressions including trigonometric, exponential, and logarithmic functions Hard: Analyze composite and piecewise functions with minimal hints Graph Detective features a custom math input interface optimized for learning, optional hardware keyboard support, and a built-in cheat sheet that explains common graph patterns and transformations.
