The Associative Property of Addition comes up when you add three or more numbers together. Because of this property, you can add any two of the numbers together at a time: (2 + 3) + 5 = 2 + (3 + 5). You get the same answer no matter which two numbers you add first.
The commutative property states that you can change the order of numbers when multiplying and the product doesn’t change. The associative property states that you can change the groupings when multiplying numbers and the product doesn’t change.
The distributive property says that if we multiply two individual numbers that we are adding together by one multiplier, we will get the same result as when we multiply the total of those two numbers by the same multiplier.
Sal introduces independent and dependent variables: how to identify the independent/dependent variable in a given setting, and how we write equations with the dependent variable by itself.
Did you know that if you know the constant and the independent variable, you can figure out the dependent variable? It's true! Watch this video and see for yourself!
This video will explain in detail the foundation of what a function is in algebra to include how to evaluate a function and what the domain and range represent with respect to functions.
A function is a rule that links one number (or a set of numbers) to another number (or set of numbers) in a particular way. Confused? Watch this video to get some clarity!
