Mathematics Tool is a program to solve systems of equations, rule of proportion problems (also called "Rule of Three" when three lines are used) and to compute a linear equation through 2 given points (A,B) or a point A and a given slope m. Entering data is based on a spreadsheet-like user interface with 3D graphic support (when necessary). Included is a square term game (with score) with 3 difficulty levels that can be selected using tabs. Additional single-step subtask support for the 'easy' difficulty level (activated by swiping over textlines), where the solution of each subtask is asked separately (e.g. '256 / 16 = ?' or '? * ? = 121' ). Another feature offers the option to find the solution(s) of a*x^2 + b*x + c = 0 or a * ( x + b ) ^ 2 + c = 0 . Implemented is automatic conversion of the factors a,b and c when switching between the 2 types and graphical output for f(x) or optional a set of f_i(x) curves (where a selectable parameter goes through the values i=-5 to 5 in steps of 1). The function graph display supports zooming in and out by 'pinching' with 2 fingers and shows the numerically computed integral value for f(x) from x-axis intersection x1 to x2 , the area value ( = | integral(x1,x2) | ) and the rotational volume. Additionally implemented is a function to generate a table for "ordinary annuity" payments and an interactive tool to compute sides, height, area and volume values of a right triangle (2D) , a pyramid , a cube or a cuboid (all 3 objects with interactively rotateable 3D images) and a circle/cylinder. Automatic unit conversion to one common unit is done by the computer and the specific steps that are necessary for the solution are given out symbolically ( e.g. 'q = b*b / c' ). The commonly used "a/b" button is provided for entering fractions and a "Shift" button lets the user switch between single-step and complete solutions. legal notice: the application logo (showing a water wave) has not been - and cannot be - created with the current version of the Mathematics Tool (but you can already get nice images using the "multi-graph" option).
