Algebraic manipulation of functions and using composite functions.

In this video, students will learn about unit rates by exploring real-world examples. The video explains that ratios compare numbers, while rates compare different units. It provides examples such as comparing the price of a gallon of...

In this video, the teacher explains how to solve subtraction word problems by identifying key phrases. The teacher emphasizes the importance of understanding the problem as a whole and not just relying on key words. Examples are given to...

In this video, the teacher explains how to simplify a rate to its unit rate using diagrams. They emphasize that a unit rate is a comparison of one quantity to another, reduced to something over 1. The teacher provides examples and...

In this video, the teacher explains how to solve equations by using the distributive property of equality. They demonstrate the process step by step, showing how to remove parentheses and simplify expressions.

This live-action video program is about the word Vectors. The program is designed to reinforce and support a student's comprehension and retention of the word Vectors through use of video footage, photographs, diagrams and colorful,...

Our modern decimal number system is base-10. Other number systems used in fields like computer engineering are base-2 (binary), base-8 (octal) and base-16 (hexadecimal).

In this video, the teacher explains how parentheses are used to write algebraic expressions and ensure clarity in their meaning. The teacher demonstrates how to write the expression "three less than a number, times twenty" using...
