A system of linear equations in matrix form can be simplified through the process of Gauss-Jordan elimination to reduced row echelon form. At that point, the solutions can be determined directly from the matrix, without having to...

New research from the Technical University of Munich has found that the amount of computing power needed to mine bitcoin produces roughly the same amount of carbon emissions as a major city like Las Vegas. <br/>

We will learn how to graph a quadratic in vertex form and graph a quadratic in standard form by completing the square and rewriting the equation in vertex form. When the quadratic is in vertex form we learn how to identify the axis of...

👉Learn how to solve a system (of equations) by elimination. A system of equations is a set of equations which are collectively satisfied by one solution of the variables. The elimination method of solving a system of equations involves...

👉 Learn how to divide mixed numbers. To divide mixed numbers, we first convert the mixed numbers to improper fractions. After we have converted the mixed numbers to improper fractions, we can then multiply the first fraction by the...

In this video, we will cover translation.

This video is a review of basic arithmetic for the purpose of solving problems on the quantitative reasoning section of the GRE revised General Test. This video covers the basics of fractions. Topics covered include: The definition of a...

This week on Blockchain Central: we are going to take a look at the controversial Tether - a cryptocurrency that is backed by the US dollar. We’ll describe it, discuss its goal, and learn about the Proof of Reserves mechanism

In this video, the teacher explains how to use a scale factor to find the area of a scale drawing. They demonstrate how multiplying the length and width of a figure by a scale factor does not generate the scaled area. Instead, they...

This video provides an overview of different sampling methods and how to choose the appropriate method for a given situation. It explains simple random sampling, systematic sampling, stratified sampling, cluster sampling, convenience...

This video explains how to solve exponential equations by using the properties of exponents. It covers various examples and demonstrates different strategies to find the value of the variable that makes the equation true.

👉 Learn about the rules of exponents. An exponent is a number which a number is raised to, to produce a power. It is the number of times which a number will multiply itself in a power. There are several rules used in evaluating...

In this video lesson, students will learn how to generate equivalent fractions using area models. The teacher explains the concepts of numerators and denominators, as well as common mistakes students make when comparing fractions.

In this lesson, students will learn how architects use scale factors to draw designs with correct dimensions. They will understand the concept of ratios and how to write them in different formats.

In this video, we explore the concept of equivalent expressions and how to use the distributive property to expand and simplify them. We demonstrate how to break down the expression into groups and then multiply to find the simplified...

In this video playlist I show you how to solve different math problems for Algebra, Geometry, Algebra 2 and Pre-Calculus. The video will provide you with math help using step by step instruction. Math help tutorials is just what you need...

FT financial editor Patrick Jenkins explains what the battle between Brussels and the UK is about over the future relationship of the City of London with the EU, and why EU chief negotiator Michel Barnier has rejected the UK's ‘enhanced...

ACT SAT Prep how to use the ratio to determine the correct data sample

👉 Learn how to solve exponential equations. An exponential equation is an equation in which a variable occurs as an exponent. To solve an exponential equation, we isolate the exponential part of the equation. Then we take the log of both...

New research from the World Wide Fund for Nature and the University of Newcastle, Australia suggests that humans consume roughly 2,000 pieces of microplastics, or five grams of plastic, a week. <br/>

In this video, the teacher demonstrates how to use addition and division to solve real-world problems involving rational numbers. They explain concepts like equivalent fractions and order of operations, and provide examples of applying...
