The Order of Operations is Wrong

An introduction to group theory, and the monster group.

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

The enigmatic equation e^{pi i} = -1 is usually explained using Taylor's formula during a calculus class. This video offers a different perspective, which involves thinking about numbers as actions, and about e^x as something which...

What happens when you multiply shapes?

Having trouble remembering the order of operations? Let's raise the stakes a little bit. What if the future of your (theoretical) kingdom depended on it? Garth Sundem creates a world in which PEMDAS is the hero but only heroic when in...

The Order of Operations is Wrong

After years of experiments, you’ve finally created the pets of the future – nano-rabbits! They’re tiny, they’re fuzzy ... and they multiply faster than the eye can see. But a rival lab has sabotaged you, threatening the survival of your...

Today we're going to discuss the Binomial Distribution and a special case of this distribution known as a Bernoulli Distribution. The formulas that define these distributions provide us with shortcuts for calculating the probabilities of...

Paul Andersen shows you how to use the rules of multiplication and addition to correctly solve genetics problems. The rule of multiplication can be applied to independent events in sequence. The rule of addition can be applied to...

What happens if you multiply things that aren't numbers? And what happens if that multiplication is not associative?

New ReviewUnderstand how multiplication and area are related is very helpful to understanding the factoring process

New ReviewIn this video I am going to show you how to determine what the missing number is given the percent.

New ReviewFollow 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

New ReviewWhen students are simplifying rational expressions this is one of the most classic mistake I see students make.

New ReviewIn this video I will expose the difference in what simply adding a power can do to simplify an expression. We will break down expanding the same binomial to the 2nd and third power.

New ReviewSome problems you should type out and some type of problems you should be able to do in your head

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

New ReviewI see students make these type of mistakes all the time when they are first learning rules of exponents and even years after.

In this math video we will write and simplify a complex fraction to find unit rate. We are given a relationship and asked to find the unit rate. We will write the relationship as a ratio in fraction form. Since one of the quantities...

This video provides an elaborate and detailed solution to the practice exercise of the rule of multiplication concept.
