In this video the instructor shows how to solve multi-step equations. In a multi-step equation, the equals to sign divides the two sides of the problem. To solve this kind of problem, the first thing you do is to get all the variables on one side and the numbers on the other s ...more

This is a mathematical instructional video on finding the point slope form of a line equation. This technique allows you to find the x and y intercepts of a line. The point slope form is (y-y1)=m(x-x1). The instructor tells you what each of the variables represents, and shows ...more

In this video the instructor shows how to solve mixture problems using two variables. Usually in these kind of questions the problem statement goes like, if A costs $x for a pound and B costs $y for a pound, in what ratio should they be mixed such that one pound of the new mix ...more

In this tutorial the instructor shows how to solve percent equations. The general form of a percent equations is that a is b% of c. As there can be three kinds of variables a, b, c, the questions involving percent equations can be of three types having one of the three variabl ...more

In this video the instructor teaches about direct and inverse variation. Two variables x and y are said to be in direct variation with each other if you can write them in the form y = K * x. The value of y varies directly corresponding to the value of x. Y is said to be direct ...more

In this video the tutor shows how to add and subtract monomials. He says that to add or subtract monomials they have to be similar terms. Similar terms are those that have same variables and equal exponents to the variables. He shows how to do this using illustrative diagrams ...more

In this video tutorial the instructor shows how to solve equations by the comparison method. In this method he isolates either the x or y variables in both the equations and now compares the other side of equations directly to derive the value of the other variable. Now this d ...more

Watch this video to learn how to create OOP design with C++. This video also covers public and private variables and functions.

In this tutorial, learn to setup private properties(variables) and private methods(functions) with your PHP OOP programming. This tutorial will have the file logger run through some private methods. Check it out and open the door to the world of PHP programming.

Arrays are little pockets of data distributed throughout your program. They're useful because having arrays keeps you from needing to work with hundreds of variables when programming. This specific tutorial shows you how to work with arrays when you're using Java to program.

So you've mastered variables, and now it's time to take a look at functions and how they work on the very basic level in Python. This tutorial also takes a brief look at importing modules, and how they work in your Python program.

So you've already mastered variables and functions - now it's time to progress to strings, substrings and slices when you're working on a program using the Python programming language. Python strings are much less complex than in other languages, which makes them easy to use.

In this clip, you'll learn how to employ variables and arrays to generate a form letter when coding in PHP. Whether you're new to the PHP: Hypertext Preprocessor scripting language or are a seasoned web developer merely looking to improve your chops, you're sure to find benefi ...more

If you want to learn how to program in the Java language, then the first thing you're going to need to do is download and install the JDK. That stands for Java Development Kit, and is the basis for anyone begging in Java, and you need it to get the Javac (Java compiler) runnin ...more
