4434Whole Calculator
http://www.merlot.org/merlot/viewMaterial.htm?id=850283
Calculator in the set of the natural numbers (ℕ). And is able to write all the natural numbers with words.When the result leaves the set of natural numbers, this calculator points to the need of to upgrade to a calculator with more features. ( ℤ calculator or ℚ calculator).Type the numerical operations and results in words.Writing numbers :The app writes correctly from from the one (10^0) until the centillion (10^303).Apples And Oranges 1 Decimal App for Android

This application is a basic tool for teaching algebra.Trying to solve a system of linear equations with two equations and two unknown variables. (Two purchases)It contains:. A button that generates new questions (״two new purchases of fruits״).. Two drop-downs to select a solution and a button to verify: The verification button checks the solution, and adds it to the list of the session.You can edit the statements. The program checks if the determinant of the proposed statement is nonzero.. The 5 tools to help resolve the problem:* Tool 1: Gauss-Jordan elimination:The two equations are represented as two purchases of fruits.Contains tools to add one column to another, multiply, divide and change the sign for to get to have one apple on a side and and an orange at the other.The result of the two additions are the values of apple and orange.* Tool 2: Graphic:Contains a graphic frame and 2 drop-downs to find the solution, using the method essay / error.The problem posed is a linear system of equations, so the results must be ever into two lines that intersect.To get the answer, one should find this point.You can also click directly on the chart.The graph is divided by the diagonal.Below the diagonal, apple values are entered, for to get the values of the orange.Above the diagonal, one enters the price of the orange.The meeting point of the two lines is represented by a yellow dot.* Tool 3: Two weighing scales:Shows two weighing balances. On the left, due to its drop-down, which determines the value proposed for apples: results gives the price of oranges in terms of the two equations.The right hand scale gives the results from the proposed price for oranges.When a scale is balanced, gives the results of both the price of the apples and oranges.* Tool 4: Cramer's Rule:This tool solves the problem at once.Contrary to what happens in other tools, here we have to manually enter the data of the problem. The two equations (two purchases) are represented in horizontal rows.If you have not entered data, the tool warns that you can not solve the problem.It can also warn when the determinant is zero:The determinant is zero when the two lines that we saw in the graphical tool, are not crossing. This happens when they are parallel. And the lines are parallel when a purchase (equation) is linear function of the other. (eg 1 A + 2 O =n1 and 2 A + 4 O = n2)The program automatically never generates such problems.* Tool 5: Inverse matrix:The tool represents the terms of the equation automatically and in landscape format (each purchase is a row)The resolution tool there are the terms of the two equations on the left and the identity matrix at right.The objective is to calculate the inverse matrix.This is achieved by operating the rows, until the data from the equations (on the left) become the identity matrix.At this time to the right we have the inverse matrix.The multiplication of the results vector by the inverse matrix gives the solution.This app costs $1.25Perceptual Processes in Reading
