An equation is like a sentence, just using a different language. Mathematical equations are telling you to do something, giving you information on how to respond, or come up with an answer. It's up to you to learn this language. However, once you know it, you can write in this language! You, too, can write […]

Algebra equations are all almost always solved by simplifying the equation first. To simplify means to make it easier to understand and solve by putting the equation in its simplest form. It requires a step by step process that is easy to follow and often straight forward. There are some common methods used to simplify […]

An imaginary number is essentially a complex number - or two numbers added together. The difference is that an imaginary number is the product of a real number, say b, and an imaginary number, j. The imaginary unit is defined as the square root of -1. Here's an example: sqrt(-1). So the square of the imaginary unit would […]

In mathematics, there are various metrics used to simplify or explain events or outcomes - especially those that involve changes or comparison. Some of these metrics include ratios, percentages, and percentage points. Ratios express the quantitative relationship between values by showing how many times one is contained in another. Percentages are similar to ratios, but they're […]

The mathematical study of calculus requires a deep understanding of a fundamental concept: derivatives. For some, the idea of derivatives in calculus comes naturally; it becomes an intriguing idea with countless applications to understanding the real world. For others, it’s merely a source of confusion or unnecessary stress. Due to their fundamental application to calculus, a […]

The mathematical term operator refers to the various symbols used in arithmetic and other branches of mathematics to represent a type of mathematic manipulation. This definition, however, does not capture all aspects of mathematics. The widespread use of operators in programming and physics makes the meaning behind "operator" too big to be described in a few sentences. Regardless, an operator in […]

Unmatched math delimiters. Adding final one for you. The simple answer is: yes you can get negative numbers out of square roots. In fact, should you wish to find the square root of any positive real numbers, you will get two results: the positive and negative versions of the same number. Writing a Square Root Equation for […]

Ah, Algebra. What a pain it can be to memorize formulas and how to solve them. For those who did not like math class, “I’m never going to use this!” runs through your mind as you do your homework. But guess what, you do use it and probably don’t even realize it. You even use it to do […]

Mathematics has helped humans perform basic tasks since its inception. It helps us with finances, cooking and baking, problem-solving, and even time series forecasting. However, none of these beat the fact that math improves our critical thinking skills, as well. Just as your body needs physical exercise to perform well, the human brain needs mental training to […]

There are two ways of solving an equation: the addition method and the substitution method. Here, we’re going to take a look at the addition method. The addition method of solving equations is an easy and simple method used in algebra. It’s also called the elimination method. Understanding the Parts of an Equation Before we learn how to use the […]
