# Description

MATH 42 helps over 2.200.000 middle-school, high-school and college students, to solve their math problems and get better grades at the fraction of the cost of a private tutor. MATH 42 helps with (1) intelligent approaches to the solution, (2) step-by-step solutions of their problems (3) an Assessment Center.

MATH 42 is a trusted mathematical resource around the world and the numbers prove it: Over 2.2 million downloads, used on over 450.000 tablets in schools, in cooperation with the biggest educational publisher in Germany (Klett).

FEATURES

• Intuitive entry of formulas

• Intelligent suggestions on how to approach a problem (unique worldwide)

• Detailed step-by-step solutions, that adapt to a student’s need (unique worldwide)

• Extensive corresponding mathematical explanations with examples

• Interactive graphs, that visualize problems

• Automatically generated and curated assessment, that enables and facilitates rapid progress

• Instant-Calculator, that computes during the entry

ASSESSMENT CENTER

• Exercises — subdivided by topic and level

• Training mode — afterwards, each problem can be analyzed step-by-step

• Test mode — enabling the identification of strengths and weaknesses

• Test results and statistics show progress over time

• Tests and exercises were created in cooperation with experienced pedagogues and private tutors
