This app is mainly designed for the studentswho need to be proficient in algebra and who need to pass thecompass math test.The app composed of two sections: Practices and DiagnosticTests.Practices section covers 24 topics in pre-algebra and algebra andeach topic consists of 5 practice questions.You can work on each exercise until you get the correct answer. Adetailed solution also included for each and every question.There are two separate Diagnostic Tests for pre-algebra andalgebra. Each test consists of 15 questions and it will display howmany questions you did correct and what are the questions that youdid wrong. These tests are based on actual compass mathematicsexams.

This app solves the Quadratic Equations byfactoring. A detailed explanation is also included. This will findonly the real roots. If the roots are complex a message will bedisplayed.Instructions:All the coefficients need to be entered.If a coefficient is 1 need to enter 1.If a coefficient is negative need to enter the number with thenegative sign (e.g., -3)

This app performs following tasks.1) Convert a decimal number to binary, octal andhexadecimal2) Convert a binary number to decimal, octal and hexadecimal3) Convert an octal number to decimal, binary and hexadecimal4) Convert a hexadecimal number to decimal, binary and octal5) Binary addition (unsigned)6) Shows truth tables for AND, OR, NAND, NOR, XOR, XNOR gates7) Shows all the properties of Boolean algebra (e.g., Identity,distributive.....)Number-Base conversions work for numbers that has both integerand fraction parts.

This app solves basic percent problems. Forexample what percent of 60 is 30? A detailed explanation is alsoincluded.

This app finds the following.1) Slope, when two points are given.2) The equation of a straight line, when the slope and a point aregiven.3) The equation of a straight line, when two points are given.A step by step explanation is included in each type.Note:Users are allowed to enter only integers (No fractions).

This app covers following topics and explain50 examples.1) Conversion between exponential and logarithmic form2) Properties of logarithms3) Evaluate logarithms4) Solve Exponential Equations5) Solve Logarithmic EquationsThis is a video and hence a single click to see all theexamples.

This app finds the factors of TrinomialI,Trinomial II and Difference of two squares. A step bystepexplanation is also included. This can find only real factors.Ifthe factors are complex a message will be displayed.Instructions:All the coefficients need to be entered.If a coefficient is 1 need to enter 1.If a coefficient is negative, the number should be entered withthenegative sign (e.g., -3).

This app performs the following tasksofphasors (or complex numbers).1) Transform a Phasor to rectangular form or polar formorexponential forme.g., if the user enters a phasor in polar form it cantransformsinto rectangular form and exponential form.2) Add or subtract or multiply or divide two phasorsinrectangular form or phasor forme.g., if the user enters two phasors in rectangular form, theappwill give the answer in both rectangular form and polar form.Atthe same time it will give the polar forms of the two phasorsthatthe user enters.3) Find Reciprocal or Square root or complex conjugate ofaphasor in rectangular form or polar forme.g., if the user enters a phasor in rectangular form, the appwillgive the answer in both rectangular form and polar form. Atthesame time it will give the polar form of the phasor that theuserenters.Instructions: Enter the phase angle in degrees. No need toenterthe degree symbol ('o').

This is a Math Radical calculator. This appcansimplify radicals, multiply two radicals, divide or rationalizearadical. It will also show all the steps along withtheanswer.

This app shows examples of three variableandfour variable Karnaugh maps. It shows a step by step processofdrawing k maps, how to do grouping and how to find thesimplifiedexpressions.This one runs as a video and hence only a single click to seeallthe examples.
