Lesson 3: Parts of algebraic expressions

# Terms, factors, & coefficients

In math expressions, terms are the components added or subtracted, factors are the elements multiplied within each term, and coefficients are the numbers multiplying variables. Understanding these concepts is crucial for effective communication and problem-solving in mathematics. Created by Sal Khan.

• define interger
• An integer means a whole number or a negative number, as long as it isn't a fraction or a decimal.
• Can someone clarify what a factor is?
• here's a song my teacher made up wich is really helpful for remembering factors,"factors are the numbers that you multiply to get the product."
• Hey, I really need help with coefficients, they're hard to understand.
• I will try my best to have this make sense:
coefficients are the number when you multiply a number and a variable. For example 5a the coefficient in that term is 5 if you have 48e the coefficient is 48. So the coefficient is the number when you multiply a number times a variable.

I hope this helps!!😀
• What of Constants? Or are "Terms" constants?
• It's more like the other way around. A constant is something like '5', where it won't be affected because of variables. A term can be a constant, but not always is. A constant, however, can be a term. :)
• Why is the coefficient so important?
• Sometimes, when an equation like 4x+4=0 pops up, it would be easy to write it like this: 4(x+1)=0 to find x. Though it might not seem important right now, coefficients can help simplify an equation. To me, it seems that the coefficient would be most useful when finding the value of a variable using factorization. I do not know many other ways a coefficient would be used but it is still important.
Edit: Also, like 6x, it's a big pain to writing it x*6 every time, so it's more practical and neater, helping organizing your equations so you don't mess up!
• What's the point of this?
• You'll need to understand terms, factors, and coefficients for Algebra I and subsequently Algebra II. It will help you gain an alleviated understanding of equations as well as the relationships between certain variables. For example, this information will be necessary for learning how to combine like terms and factoring quadratics later on.
• I’m just a clueless 5 th grader who started using this and how the heck do I get out of this video? I just wanted to understand what I was doing
