## Equations of Parallel Lines

Non-vertical lines, or lines that have positive, negative or undefined slope, are parallel if they have the same slope and different y-intercepts. Vertical lines, which have zero slope, are parallel if they have the same slope and different x-intercepts.

## Prime Factorization

This tutorial is on prime factorization and how to do it step by step. This is a really important process and one that can be very confusing at times. One can easily mess up and get the wrong answer. So let’s jump right in and learn the concept of factorization!

## Solving 2-Step Equations

Solving 2-Step equations may seem hard at first but becomes really quite easy after you get the hang of it. It simply consists of isolating the variable within the equation.

## Order of Operations

Order of operations is a building block for basic mathematics. Without this skill math can become difficult and result in the incorrect answer. We use the mnemonic PEMDAS to learn this skill. PEMDAS identifies order of operations reading left to right. P; Parenthesis E; Exponents M; Multiplication D; Division A; Addition S; Subtraction Follow this…

## Solving problems

This example is helping first graders how to add. The example will be shown step by step and gives the child a first had look at how to solve an addition problem.

## Conic sections : vertices, foci and eccentricity of an ellipse.

From the equation of a conic section, here an ellipse described by 9x^2 + 36y^2 = 324, we will find vertices, foci and eccentricity. Given the equation, an oval of center (H,K) can be traced. A path of points traced (x,y) so that the sum of its distances from two fixed points is constant. The…
