Thanks for watching! In this video I explain the total revenue test, elasticity of demand, elasticity of supply, cross-price elasticity, and income elasticity. Make sure to pause the video and try to answer the seven questions on your own.

Explaining negative numbers.

Number systems evolved from the natural "counting" numbers, to whole numbers (with the addition of zero), to integers (with the addition of negative numbers), and beyond. These number systems are easily understood using the number line.

In this video, the teacher explains the concept of restrictions on the domain and range of functions. Using the example of Emily purchasing music albums with a gift card, the teacher demonstrates how certain values of x can make a...

How to solve algebraic inequalities.

This video explains how to subtract negative numbers using integer chips. It demonstrates the concept of zero pairs and shows how to add and subtract integers with like and different signs.

In this lesson, students will learn how to solve quadratic equations by inspection. They will review the concept of perfect squares and understand that both positive and negative numbers can be multiplied to obtain a perfect square.

In this video, the teacher explains how to subtract negative numbers using a number line. They provide examples and real-world scenarios to help students understand the concept. The lesson emphasizes the direction of movement on the...

This video uses real world examples to define and describe integers. Students will learn that an integer is any whole number can be positive, negative or zero. Viewers will come to understand that integers have important properties that...

In this lesson, students will learn about reflections in linear equations. They will explore how the functions F of X and G of X are alike and different, focusing on the slope and Y-intercept. Through examples and a table of values,...

This video explains the concept of integers and demonstrates how to graph the addition problems on a number line. Students also learn to consider the absolute value of the addends to determine whether the answer should be positive or...
