The growth function uses exponentiation to determine a value which will be achieved in the future. This app allows to enter a starting value, a resulting value, growth factor, growth rate, percentage rate and a time value. To lower the complexity the calculations of the growth factor, growth rate and the percentage rate are divided in 3 different modes. The missing value will be calculated step by step. If it growths or decays depends on the input you deliver. The app also creates a graph to give an impression of your function. An infographic shows how your input affects the growing or decaying of your starting value. 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. [ Contents ] - modes for considering the growth factor, growth rate or percentage rate - the missing value will be calculated - results are calculated and shown in detail - infographic to explain the parameters - a graph of your function - history function to save the input - detailed solution - negative values, decimal numbers and fractions 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
