In this video, the teacher explains how to solve multistep problems involving positive and negative rational numbers using the order of operations. The teacher addresses common mistakes students make, such as confusion with addition and...

With the Passerini and Ugi reactions down, let's learn one more multi-component reaction, the Biginelli reaction. Developed by Pietro Biginelli in 1891, this reaction produces pyrimidine derivatives. What's the mechanism? What are the...

Looking at how addition reactions occur on conjugated polyunsaturated systems.

This video is a review of Two Dimensional Vectors. This video goes vector operations also known as vector arithmetic. Topics include: geometric interpretation of scalar multiplication of a vector, vector addition, and vector subtraction.

Exponentiation is shorthand for repeated multiplication, just like multiplication is shorthand for repeated addition. Multiplied or divided exponential terms with like bases can be combined by adding or subtracting their exponents.

Learn how to solve the particular solution of differential equations. A differential equation is an equation that relates a function with its derivatives. The solution to a differential equation involves two parts: the general solution...

In this lesson, you can learn how to use linking words and phrases for the IELTS writing exam. Linking words are important for your IELTS writing, especially for the essay. Using linking words well can make a big difference...

In this video, the teacher explains how to solve multistep problems with positive and negative decimals using the order of operations. They emphasize the importance of understanding the correct order of operations rather than relying on...

Astronauts onboard the ISS get their breathable oxygen in two main ways - through systems onboard the ISS that generate breathable oxygen and through resupply missions that deliver breathable oxygen to the ISS. There is plenty of oxygen...

It's been called "the Queen of Sciences"--mathematics. It might not be as obvious in Olympic sports as physics or materials-engineering, but math--from simple arithmetic to calculus--is part of every jump, every spin, every move the...

You can think of programming like extra powerful math. Instead of working with just numbers, you can work with many different kinds of data. Just like math, programming uses special symbols called operators to make changes to...

Understand the concept of degree and how it relates to the exponents in polynomial terms. Through examples and the use of algebra tiles, students will practice adding polynomials and see that the sum is always a polynomial.

This video explains how to add mixed number fractions with different denominators using area models. The students learn that they need to find a common denominator before adding the fractions, and they are guided through the process of...

👉 Learn about solving logarithmic equations. Logarithmic equations are equations involving logarithms. To solve a logarithmic equation, we first use our knowledge of logarithm laws/properties to express the terms in both sides of the...

Learn how to determine the resultant vector by adding, subtracting and multiplying vectors by a scalar. We will also learn how to graph the resultant vectors to show the operations. Vectors can be added, subtracted and multiplied. To add...

When we experience anxiety, our sympathetic nervous system is activated and initiates the fight-or-flight response. This response is a host of physiological changes that prepare us to either fight or flee. One of the effects of the...

👉 Learn how to determine if an equation is a linear equation. A linear equation is an equation whose highest exponent on its variable(s) is 1. The variables do not have negative or fractional, or exponents other than one. Variables must...

This Video Explains What the Bargaining Mix is

👉 Learn how to find the derivative of a function using the chain rule. The derivative of a function, y = f(x), is the measure of the rate of change of the function, y, with respect to the variable x. The process of finding the derivative...

This video lesson teaches students how to find the area of a rectangle using multiplication and addition. It provides clear explanations and examples, guiding students through the process step by step.

In this video, the teacher explains how to estimate the addition of fractions using benchmark fractions. By visualizing 1/2 as a reference point, students can determine whether their answer should be larger or smaller than 1/2 based on...

In this lesson, students will learn how architects create scale drawings using fractions and decimals. They will understand the concept of a scale factor and how it is used to enlarge or reduce dimensions.
