## Evaluate variable expressions involving integers

Starting with the basics is variables (symbols for an unknown number, usually a letter like x or y) involving integers (an integer is a whole number, not a fraction). “Evaluate variable expressions involving integers” is the same as saying “solve for x using whole numbers”. With this, we need to know the following: 1) We…

## Evaluate variable expressions involving rational numbers

Variable expressions involving rational numbers are one of the first lessons in Algebra 2. A rational number is basically a fraction or a decimal, but it can’t repeat forever (infinity). Technically, it’s “any number that can be expressed as the quotient or fraction p/q of two integers.”-mathforum.org. For example, .8, which can be expressed as…

## Solve Absolute value inequation.

The absolute value has two parts so like |x| can be written as x for x>=0 and -x for x

## Introduction to Complex Numbers

Consider the equation x^2=-1. Since squaring any number is 0 or larger, no real number will make this equation true. Create a number i such that i^2=-1. By “adding” i to the real numbers, the complex numbers (having the form a+bi where a and b are real numbers) are created. Visually represent a point a+bi…

## Factoring Polynomials

Factoring polynomials is extremely important in your growth as a mathematician, but why? When we factor polynomials, we are finding the zeros of the function – meaning we are finding the places where the graph of the function crosses the x-axis.

## Systems of Linear Equations

Systems of Linear Equations is a common problem you will see in algebra courses, even up to the college level. You are usually given two linear equations and must find their intersection to solve the system. I find that students don’t often struggle with these problems until they are in the form of a word…

## Verbal Problems Solving for two unknowns with two equations

This Tutorial I wrote presents six problems with increasing difficulty that use Substitution and Elimination methods to obtain both unknowns. I will break it up into two parts.

## EXPONENTS

This tutorial will not give the solution to a specific problem. Rather it will show how we define the definition of a number raised to the zero power, a fractional power or a negative power.

## A Complicated Logarithm Problem

I hope you know that the following theorems are true We are going to use all of these theorems to simplify a complicated logarithm expression
