✅ Just a reminder for when you’re writing expressions... you want to write any variable terms first and constant terms go last. If there are multiple terms that involve variables, they should go in order from greatest to least as far as exponents. If any exponents are the same, go in abc order. For example, #4, we have a variable of c and a variable of d. They both don’t have an exponent written, so they go in abc order (remember, if no exponent is written, there is an understood exponent of 1).

✅ For #4, we can also think through the distributive property by distributing the -8 to to the -c, which gives us 8c. Then, we can bring down the subtraction sign. Next, we can distribute the -8 to the d. That gives us -8d. So we end up with 8c - (-8d). Now 8c - (-8d) is correct, but remember, subtracting a negative is the same as adding a positive, We can change subtraction to adding the opposite, so we can rewrite this as 8c + 8d. We can rewrite the subtraction of a negative as adding a positive in order to get rid of the double sign (this cleans up the expression and makes it a little simpler). So you can see, we get 8c + 8d that way as well. To recap, 8c - (-8d) is correct and equivalent to 8c + 8d, we can just rewrite that double sign as one. Subtracting a negative is the same as adding a positive.

✅ Thanks so much for watching! ✌✌✌

This channel made math so much easier when I um... didn't pay attention in class....

I spent hours after being given this lesson by my teacher practicing again and again and just couldn't get it. I don't blame the teacher because how she gave it is how she learned it. But after only 1 lesson here with Mr. J and only 4 examples, I GOT IT!!! Thank you, a million times.

Thanks Mr J, you are a wealth of knowledge and you know how to brought across the subject matter. I am well on my way to tackle factoring and polynomials.

These are the math expressions I needed more practice with to understand them clearly

Tbh I need someone like this as my teacher that can just make me understand best teacher every. (Not saying my teacher is bad or anything). Also do you have a video on dimensional analysis /w conversion factors bc I need to learn that asap before a trimester final. If you have one could you send me a link because I’m just too blind 😅

[Compuscience-Python-Prog-Exps]

Yeah. I got these all right. I've still got a bit of school in me. I just didn't
step on the podium, but I did graduate and got my Gd 12.

This video is cool and all, but don’t let that distract you from the fact that Gru is the most powerful being. According to the height of a Minion (which is 3.5 feet on average) Gru is 4 minions tall, which means he is a godly size of 14 feet tall. Second, If any of you remember the original Despicable Me, you know there is a scene when Vector kidnaps the three girls and shoots a series of heat-seeking missiles at Gru, he then dodges them all. According to the speed of an average ballistic missile (1900 mph) and the size of the missile according to his ankle size, Gru can perceive and move at such a speed that the missiles can only move 9.5 miles per hour, 0.5% of their original speed. Plus after this Gru punches a shark and it is paralyzed meaning it’s spine is probably shattered, to remind you it would require a force greater than 3, 000 newtons to fracture the spine. That’s equal to the impact created by a 500-pound car crashing into a wall at 30 miles per hour. I have to come to conclude that Gru is the most powerful being in the universe.

I didn't understand 2part
So, where 18x is. Plz reply 😢

Dk why but when I think of Mr. J i vision Harley Quinn saying it. Makes his name cooler, thanks for the helpful vids tho.

[Zeebucks]

you helped me on 7-8 subjects I think😂

[pangwen]

thx idk why I didnt understand these lol
