Mathcracker.com is a cornucopia of math tools, calculators, solvers, and tutorials all in one

place that is a one-stop solution for the vast majority of math calculations and operations that

the student or professional needs to perform, whether for assignments, theses, reports, or

professional documents. The tools run the gamut from basic to advanced math calculations,

with 120 tools and growing. The solvers, graphing tools, and “math cracks”, which are

Mathcracker’s signature form of plain English tutorials, are all accessible from an easily

navigable menu bar with drop down menus. The number and high quality of the tools are

quite impressive, and all the tools are available for free!

To give an idea of the range of tools you can choose from, starting with the categories of

algebra, calculus, statistics, or probability calculators, you are then led to a variety of

calculators and solvers under the same category. You’ll find calculators for cross product, dot

product, permutation coefficient, factorial of a number, absolute value, algebraic expression,

angle conversion between degrees and radians, arithmetic sequences, area and volume of a

circle, cone, cube, and cylinder, and the list goes on and on. For probability and statistics,

you’ll find 11 pages of tools, including calculators for chi square test for goodness of fit,

Kruskal-Wallis test, Lamda coefficient, critical Chi square values, uniform probability

calculator, ANOVA, Cramer’s V, Z test, F test for the equality of two population variances,

relative risk, odds ratio, effect size Cohen’s d, binomial probability, and many more. There are

graphing tools for bar charts, box plots, functions, histograms, line charts, pie charts, scatter

plots, time series, and many more. To list all the tools here would take several pages, so the

recommended approach is just to go see for yourself.

Each tool comes with clear instructions on what it does, how to use it and what information to

enter. To use a calculator or solver, you enter the information you want into the appropriate

labeled form field boxes in the calculator. Each element of the calculator is labeled so you

know what information to enter and where to type it in. Upon pushing a bright yellow

“calculate” button, you are provided with the solution along with a brief explanation of the

background of the concept you are working with and how to interpret the result. If for any

reason you did not enter the right information or you are missing information, upon clicking

“calculate”, you will be presented with a message in red indicating to you what you are

missing so you can check your information. This is really helpful because sometimes

beginners or the less well-versed in math don’t necessarily know exactly what type of

information they need to solve a given problem, so the tool nudges you in the right direction.

To understand the background of the people who created this site, according to the designers

of the site, who include PhD’s with backgrounds in mathematics, statistics, engineering, and

education, the site emerged out of a desire to make math transparent and accessible to

people from many different backgrounds, including those with strong math skills as well as

those who are not so comfortable performing high level mathematics. Currently, the site is

used by students and professionals all over the world as a cornerstone math resource. They

have been linked to by major universities, teachers’ personal blogs, and included in

classroom curriculum.

The ease of use and completeness of the tools makes them compatible with the needs of a

wide variety of people and projects, and the solution and graphic outputs are of a high quality

and can be used in reports and for educational purposes. Far and away, this is an excellent

and advantageous resource for anyone who needs to perform calculus, algebra, statistics or

probability calculations for nearly any conceivable purpose, and can replace many of the

functionalities of other proprietary software programs.
