Description

MATH 42 helps middle-school-, high-school- and college-students to understand mathematics better. It helps them with homework, ahead of tests and during studies with (1) intelligent approaches to the solution, (2) Step-by-Step solutions and (3) a training- and test-mode. Exercises and solutions can be posted on Facebook and sent by eMail. 


FREE MATHEMATICAL FEATURES

All math that was free up until now will also be available for free in this version of MATH 42.

• Simplifications and transformations (Signs, combining, factorizing, binomial decomposition, …)
• Fractions (adding, reducing, multiplying, simplifying, GCD, LCM, …)
• Logarithms and trigonometric functions (rad/deg)

• Linear equations

What's New in Version 2.2.0

The update provides a complete overhaul of the mathematical explanations and definitions, which greatly enhances the learning experience of the students. It enables them to understand every concept and notion, that was formerly too difficult to grasp.
MATH 42 2.2 is 10x - 100x faster compared to previous versions, which makes MATH 42 even snappier than before.

Examples why not ready

This program is able to perform basic math and tries to show the process on how to solve the problem but it's not ready for more complex problems. I tried several problems that other calculators and apps had no problem with but this one got many of those wrong. One of the examples: 3^(x+1)=9^(x^2). Solving for x should give 1 and -1/2 but this program just subtracts one side from the other and gives 0. It can't find x and this is merely a high school algebra problem. Another one: 3x^3+2x^2-3x-2=0. Roots are -1, 1, -2/3. This app just chokes. Again this is high school algebra!

I fully understand the need to charge a fee for your time and effort in creating this app but a recurring subscription is a bad idea for this app when it's just not ready yet. There are several advanced Calculator apps that are more capable that perform symbolic algebra and calculus for a very reasonable one time fee.
