NumberGyan.com is a novel Mathematics Cloud Computing platform for learning and practicing mathematics.

Using a set of algorithms, NumberGyan.com can generate problems on each topic The problems are organised by topics and sub-topics.


NumberGyan.com has content in the areas of Numbers, Algebra, Geometry, Trigonometry, Probability and Statistics.

There is a progressive development of concepts in each topic.


  • Integers, rational Numbers (fractions, decimals)
  • Percentages, ratio/proportion, profit/loss, simple interest, compound interest
  • HCF and LCM
  • Squares and square roots
  • Cubes and cube roots
