Algebra can be fun!

Algebra Kaiser (Algebra Emperor) is a game that can vastly enhance both your basic algebraic skills and ability to concentrate. Practice your ability to handle variables, expressions, terms and simple equations. 17 different types of dynamic exercises ranging from simplifying terms to exponents, linear equations and their graphs.

17 types of exercises:

  • Adding and Multiplying of Variables
  • Common Mistakes
  • Expansion of Single Brackets
  • Common Factors
  • Exponents
  • Order of Operations
  • Binomial Theorem
  • Simple Linear Equations
  • Graphs of Linear Equations
  • Geometry: Estimating Angles
  • Geometry: Sum of the Angles of a Triangle

More Features:

  • Multiple-Choice
  • Classic Mode: Tap correct answers, cross wrong ones
  • Overview of mistakes and misses
  • Global Highscore list (monthly)
  • Learn what you need: all exercise types can by combined freely


Pick the correct answer from 3 alternatives.

Always fresh: Unlike most math trainers, the problems are dynamically generated and so are the intelligently constructed answers. So you can have hundreds and thousands of different exercises even if you only activate a few types of problems.
