The Order of Operations is Wrong

What is a vector? Is it an arrow in space? A list of numbers?

In 2019, Amazon signed the Climate Pledge, a commitment to become a net-zero carbon business by 2040. Dave Clark, Amazon's chief of consumer retail, and Kara Hurst, head of the company's sustainability efforts, sit down with entrepreneur...

Hacking, fake news, information bubbles ... all these and more have become part of the vernacular in recent years. But as cyberspace analyst Laura Galante describes in this alarming talk, the real target of anyone looking to influence...

Get to know the unique properties of quantum computers and the obstacles that have prevented this theoretical technology from becoming a reality. -- Quantum computers could eventually outstrip the computational limits of classical...

The brain of luchador Hanko wants to take on the worlds fastest supercomputer, "K," in a cage match for bragging rights - which one is the most impressive information processor?

Logarithms are confusing, but perhaps some alternate notation could make them more intuitive.

Mathematics explains the workings of the universe, from particle physics to engineering and economics. Math is even closely related to music, and their common ground has something to do with a Rubik's Cube puzzle. Michael Staff explains...

Logarithms are confusing, but perhaps some alternate notation could make them more intuitive.

A lack of infrastructure in parts of Africa has made unregulated, gas-powered motorcycle taxis widespread -- a system that gets people where they need to be, but heavily pollutes the air and excludes drivers from the formal economy. TED...

The Order of Operations is Wrong

Since Joseph Marie Jacquard’s textile loom in 1801, there has been a demonstrated need to give our machines instructions. In the last few episodes, our instructions were already in our computer’s memory, but we need to talk about how...

Today, Carrie Anne is going to take a look at how those transistors we talked about last episode can be used to perform complex actions. With the just two states, on and off, the flow of electricity can be used to perform a number of...

Today we're going to talk about a fundamental part of all modern computers. The thing that basically everything else uses - the Arithmetic and Logic Unit (or the ALU). The ALU may not have the most exciting name, but it is the...

Modern computers are revolutionizing our lives, performing tasks unimaginable only decades ago. This was made possible by a long series of innovations, but there's one foundational invention that almost everything else relies upon: the...

In this video, I demonstrate simple methods for solving linear equations containing fractions, specifically focusing on two step equations. We explore how fractions can show up in our equations and how to use problem-solving strategies...

Follow the order of operations and simplify an algebraic expression. In this video I am going to complete an easy, a medium and a hard example

In this video we are going to go over a easy a medium and a hard example of solving linear equations with parenthesis

When solving linear equations there are some basic problems as well as ones that are harder to understand and solve. In this video I want to highlight three problems that could show up on your test that you need to know.

Learn three useful tips for solving linear equations, from basic one-step to multi-step problems. The presenter demonstrates various techniques, including the "box approach" to isolate variables. These strategies help overcome common...

This video explains how to solve three different square root equations (0:00). Brian McLogan demonstrates how the placement of the radical impacts the steps to solve the equation and the final solution (0:12). He covers isolating the...

What does it look like when we have an equation with one solution vs one with two solutions.

If you need a quick refresher on solving literal equations or better understanding this video will work through three different examples.
