Algebra - Properties of Numbers

Let's get into it: all the math properties of numbers. Every major property you can think of in algebra... we got 'em. They include:
Reflexive Property
Symmetric Property
Transitive Property
Substitution Property
Additive Identity
Multiplicative Identity
Multiplicative Property of Zero
Multiplicative Inverse (aka reciprocal)
Additive Inverse
Commutative Property
Associative Property
Yeah, I know. There are quite a few Properties of Numbers in math. Fortunately, using fun and connective mnemonics I developed in my classrooms over the years, I offer some insightful ways to remember them. Later in the video, we simplify expressions, and name the property used in each step. I hope this helps you learn them well, and YAY MATH!

You've been helping me since my first year in highschool And this year is my last. I don't think i would've made it without your videos, THANK YOU❤.

[@yaymath]

What a huge honor to know, Xian. Thank you so much.

dang fr? oooo

[@aaqil1soyfoo898]

That is a great teacher.

[@bricktothehead]

Thank you for all the videos yo. Not just this one. You have helped me understand math processes so much better

[@rauldempaire5330]

Thank you for sharing this Vlogs, your material was very helpful to my daugther!

[@pourushgutta1411]

U r just superb. Great person

[@yaymath]

I appreciate your kind feedback, Pourush

[@Bnelen]

You're the best.

You can also say that 2 + 10 = 10 + 2 is demonstrating the symmetric property isn't it?

[@yaymath]

That is correct = correct is that.

@@yaymath OMG YOU ANSWERED 😭😭😭

[@osagbemisunday]

Thank you. You make learning math look so easy and admirable.

Mind blown..Not sure why school didnt think to teach us the names of the properties but hey ho its never too late

It seems the commutative property works for subtraction it we change it into addition form.

[@donaldtrumpet8191]

Explain

[@hemarajue2736]

@@donaldtrumpet8191 5-2=3. If we apply the commutative law, it becomes 2-5=-3. Hence commutative property won't work for subtraction. On the hand, if we change the subtraction into addition form i.e ,5+(-3)=2 and apply commutative law it becomes (-3)+5=2. Hence the law.

🙌 come back🤓

[@cbcimutebi5564]

no because i actually paused and multiplied in my head for 60X2.8😅

[@fardawsabaashe9182]

I were watching your videos since 2017 Until now but you stop the teaching for year.
