Several math topics are combined into one app. Choose a topic and enter your values to get the results with all solution steps. [ Topics ] - calculation of linear equations - simplification of fractions - Pythagorean theorem - calculating the solution of quadratic formulas by the PQ formula - binomial formula to calculate perfect trinomials - scientific factoring quadratic trinomials with endless solutions - rule of proportion - percentage calculation - factoring quadratic trinomials by the AC method - finding x of a mathematical term - basic operations of mathmatical fractions - calculation of all quantities of a circle and a sphere - calculation of all quantities of a right triangle - calculation of all quantities of an isosceles triangle - calculation of all quantities of a pyramid - unit circle with graphics and charts - calculation of all quantities of an arbitrary triangle - sine, cosine, tangent and its characteristics - advanced exponentiation - simple power and root calculation - simple logarithm - logarithmic identities and rules - power and logarithmic function and its characteristics - exponential growth and decay by the basic growth function - calculation of all quantities of a circular cone - calculation of all quantities of a frustum of a pyramid - calculation of all quantities of a frustum of a cone - binomial coefficient and n-factorial - Bernoulli experiment with expected value, variance and standard deviation - Bernoulli process, histogram, distribution function chart and probability tree (tree chart) - binomial distribution, success probability and complementary probability - mean, the empirical variance or the expected value, the variance with standard deviation of dataset with probabilities - combinatorics with permutation, variation, and combination - more will come ... [ Contents ] - overview of all topics - some topics contain different modes which can be selected - the missing value will be calculated - results are calculated and shown in detail - some topics contain an infographic to give a deeper insight into the topic - some topics contain a graph of your function - history function to save the input - detailed solution - depending on the topic, negative values, decimal numbers, fractions and π are supported - no ads! [ Usage ] - there are fields for entering values using a special keyboard - press the check mark button at the bottom right to start the calculation - if values are missing, the relevant field is highlighted in yellow - if the values are wrong, the affected field will be highlighted in red - the entries in the history can be deleted or sorted - if you select an entry in the history, it will be automatically loaded for the calculation - the whole history can be deleted by pressing a button - solutions can be shared - touching the question mark button displays information about the topic [ Pricing ] This app provides 5 free calculations to test the app. This cannot be reset.
