This app focuses on the basic operations: addition, subtraction, multiplication, division and changing the base of the logarithm. You need to enter all values and the app shows the usage of certain calculation rules of the logarithm step by step. There you see how the transformation of the logarithm may lead to an easier way of calculation but with the same results. An infographic contains all calculation rules of the logarithm.

Decimals, fractions and negative values are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared.
