In this math video we will write and use a real world expression with Unit Rate. We will understand that "per" means to multiply in math. We will interpret a real world situation and translate the language into a math expression. We will...

In this video, the teacher explains how to use function notation to evaluate functions and determine output values. They provide examples of using numerical inputs, expressions, and even other functions as inputs.

👉 Learn how to add and subtract polynomials by either using the vertical or horizontal method.

When Students go to evaluate a basic expression they often make a simple mistake that is very obvious and easy to miss.

👉 Learn how to deal with Rational Powers or Exponents. Exponents are shorthand for repeated multiplication of the same thing by itself. This process of using exponents is called "raising to a power", where the exponent is the "power"....
