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 math video lesson, we will learn how to simplify numerical expressions with integer exponents. Students will clear negative exponents using the idea of reciprocal location, apply the product of powers property to multiply powers...

New ReviewIn this math video we will simplify a polynomial expression by using the difference of squares property.

New ReviewHow many times can you factor a polynomial? In this video I will show you how we factor this polynomial three times and we don't expand.

New ReviewUsually I recommend that students solve simultaneous equations using substitution when an equation is not linear but in this example you can actually using substitution or elimination.

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 ReviewLearn how to compose two functions f(x) and g(x) for functions involving quadratics, rational functions and radicals

New ReviewIn this video I am going to break down a very simple and basic example to understand how long division works with polynomials

New ReviewIn this video we will explore three of the most common mistakes students make when solving exponential equations

New ReviewIn this video we are going to compare the difference of rationalizing the denominator when you have one radical vs a binomial with one radical.

In 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...

In 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...

In 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...

In this math video we will learn how to multiply a monomial by a binomial to simplify an algebraic expression. We will be presented with an algebraic expression which represents a monomial multiplied by a binomial (two term expression)....

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 video, we explore how changing a, h, and k affect the graph of a parabola (or any function, really). The "a" value controls vertical stretch, vertical compression, and reflections. The "h" controls the horizontal shift and the...
