The Order of Operations is Wrong

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

In this video Paul Andersen explains how a sine or cosine wave can describe the position of the wave based on wavelength or wave period. A wave function can the position of a wave as a function or the amplitude and wavelength or the...

Paul Andersen shows you how to calculate the standard error of a data set. He starts by explaining the purpose of standard error in representing the precision of the data. The standard error is based on the standard deviation and the...

Mr. Andersen shows you how write the chemical formula for chemical names.

New ReviewIn this shorts math video we will answer a standardized math test question where we simplify a numerical expression. We will understand that we need to simplify the expression in the parentheses FIRST. We will review that we need to...

New ReviewIn this math video we will review how to simplify a polynomial expression. We will begin by clearing the parentheses using the Distributive Property. We will review that you multiply each term inside the parentheses by the factor...

New ReviewIn this Algebra 1 math video, we’ll use the laws of exponents to evaluate a radical expression — perfectly aligned with Standard HS.N-RN.A.2.

We’re solving a problem that involves a cube root inside parentheses that’s...

A video entitled "Exponential Problems" which shows how to apply exponent rules to simplify an expression.

Howcast -Learn how to use parentheses correctly from Gotham Writers' Workshop instructor Stephanie Paterik in this Howcast grammar video.

Factoring is the opposite of distributing. If you can find a common factor, you can reduce an expression.

In this video, we use the properties of logarithms to expand expressions.

In this math video we will learn how to multiply variables with exponents. We will begin by identifying each term in the given algebraic expression. We will consider the expression inside the parentheses to determine these terms are not...

In this math video we will learn the 7 steps to solve a linear equation. We will begin by reviewing each step for understanding. Then, we will perform each of the 7 steps by solving a linear equation. An exemplar problem and solution are...

In this math video we will learn how to use exponent rules to simplify an expression. A mini focused lesson will be provided to review and learn about the Power of a Power Property. We will apply this property to an expression to...

In this math video we will be plotting points on a graph. We will learn that an ordered pair is written in the form (x, y) where x tells us the horizontal distance to travel right from the origin followed by a vertical distance of y. We...

In this math video we will identify an equivalent expression using the distributive property. We will identify each term of the given algebraic expression. We will review that the first step to simplifying will be to clear the...

Whether you're just starting out, or need a quick refresher, this is the video for you! Mrs. C will go show you step-by-step how to factor out a negative number in an algebraic expression.

We just introduced a lot of notation in order to understand post-Fregean predicate logic. So now let's look at some concepts behind this type of logical thought so that we can compare it to earlier types of logic. In doing so we will...
