Free problem-solving mathematics software allows you to work through more than 500 math problems with guided solutions, and encourages to learn through in-depth understanding of each solution step and repetition rather than through rote memorization. Tutoring material is available in three languages. A translation option offers a way to learn math lexicon in a foreign Idioma. Test preparation options facilitate development of printable math tests and homeworks, and automate preparation of test variants around each constructed test. Covered subject areas are arithmetic, pre-algebra, algebra, trigonometry and hyperbolic trigonometry. This includes basic math and advanced topics, such as solutions of linear, quadratic, biquadratic, reciprocal, cubic and fractional algebraic identities, equations and inequalities, solutions of trigonometric and hyperbolic equations and more. The software supports a number of interface styles. This program is a trial Versión of the EMTeachline mathematics software
