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 […]

Boolean functions derive from Boolean algebra, a form of mathematical logic. This is a branch of algebra in which the values of variables used can assume only truth values, i.e., true and false. It was developed for logical operations. Boolean algebra differs from other branches of algebra in that it does not use arithmetic operators such […]

An ellipse is a stretched circle, literally speaking. This is a shape that results from transecting a plane through a conical shape, and as such, both a circle and an ellipse are examples of conical sections. The conic shape of an ellipse is determined by the angle of intersection between the plane and the cone; […]

During my first year in university, I had a roommate who was majoring in economics. Among some of her reasons for choosing this course of study was the simplicity of the mathematics included -- or so she thought. The following weeks of lectures gave her a nasty shock. Mathematics is a crucial and vital part of […]

A polynomial is a mathematical expression containing variables in which the operators in the expression are limited to addition, subtraction, and multiplication; and non-negative integer powers of the variables. The variables are referred to as indeterminates since the values of the variables are unknown. Numerical values attached to the variables are called coefficients. An example […]

Before we begin simplifying radical expressions, let’s recall the properties of them. Take a look at the expression below: ​ Looking at the radical expression above, we can determine that X is the radicand of the expression. Meanwhile, √ is the radical symbol while n is the index. In this case, should you encounter a radical expression that is written like this:​ ​ You can […]
