Great question! In order to solve for a variable, we need to isolate it. The easiest way to isolate a variable in the denominator is to move it to the numerator. However, you could technically still solve for a variable and keep it in the denominator, but it's a longer, more complicated process. For instance, we can take the problem I used in the video: 30/x = 10 30 is in the numerator x is in the denominator Instead of getting rid of the denominator, lets get rid of the numerator. In order to do that, we can multiply both sides of the equation by 1/30. Why? Because we're trying to get rid of the 30 in the numerator, and we can do that by reciprocal of 30, which is 1/30. 1/30 * 30/x = 10 * 1/30 On the left side, the 30 on the top and bottom cancel out and we're left with 1/x On the right side, to multiply fractions just multiply straight across, so we get 10/30 which reduces down to 1/3 We're left with 1/x = 1/3 To get a balanced equation, the numerators and denominators have to match. The numerators match (they're both 1), so for the denominators to match, we can now see x = 3, then we get 1/3 = 1/3. So as you can see we get the same answer (x=3) but with several more steps. That's why, generally, moving the variable to the numerator is the easiest way to solve for it. Hope that helps!

lol I'm glad I could help :D

I'm so glad to hear that, and you're welcome! :D

You're very welcome! I'm so happy to hear your finding the vids helpful :D

You are very welcome! And I don't blame you, there are several math topics that are a little hard to understand at first. You need to see it a couple times before it starts clicking. I'm glad its making sense now! 🙏

You are very welcome! :D

@Fizaaahhh Great question! You're right, 3 > 3 is an invalid statement. However, the reason we plug in 3 to evaluate the point is just so the graphs lines up properly. If you want, you could plug in something really close to 3 like 3.0000001, but you're basically going to get the same answer which is why it's easier if we just use 3 to evaluate it. Also, when graphing our line on the corrdinate plane, we make sure we put an OPEN circle because thats how we show the graph doesnt actually touch or include x = exactly 3, but that it does include all numbers greater than 3. Hope that helps 👍

You're very welcome - I'm glad it was helpful!

As always, thank you very much for the kind words! 🙏 I'm glad you continue to find the videos helpful, and you are ALL very welcome! 😁

@@Eat_Pi you deserve our apreciation for your hard work was really helpful for a lot of students I i watched almost all videos you posted was really a great job thank you again.

I hope you report his/her butt to The Hauge! And you're welcome, glad I could help 😄

I'm sorry to hear that! If you give me your problem I could probably walk you through it 👍

Always happy to help 👍

It is a free math lesson 😄 Planning on giving you all a lot more of those! 🙏

lol I'm glad I could save you! 😄

lol I'm glad you liked it! I'm just happy I get to help the people who ARE looking for it 🙏

So happy to hear that! 😃

Yeah there's a lot of "random" math topics. Some help, some don't. Funny enough, this topic was actually kind of useful for me. As a civil engineer, I design the geometry of roadways - so it was an important topic to learn about tangents and how they relate to circles and curves.

While it is a little harsh, I will say this: if you don't "get" math in school then a career that doesn't need math chooses you and not the other way around. I am a chemical engineer, I couldn't have even finished the first year of my degree without calculus and Linear algebra. It's not for everyone.

Thank you I try to be thorough! 🙏

I am glad you are enjoying the content!

lol thank you!

That's an algebra topic that everyone watching this geometry video may no be familiar with. That's why I didn't use it - but yes, that is definitely another way to multiply binomials 👍

@@Eat_Pi It's a common formula in maths, used in a lot of math videos. I think most people who watch math videos know this formula. And when they don't know, never too late too learn.

lol I'm happy to help! 🙏

I'm so glad to hear it was helpful! And thank you for the support, I really appreciate it! 🙏 btw I'm always around if you ever have any questions 👍

@@Eat_Pi thanks!!!!

It's a great idea to watch a topic BEFORE class because then you have a better idea of what you're teacher is talking about. Try it out and see if it helps! And I'm always around if you have questions 🙏 lol

Good question! We know because angles along a straight line add up to 180 degrees 👍

lol well as they say, better late than never, right? :D

P.S I loved your intro "What's up you freakin geniuses" Lol🤣

I'm so happy to hear it was helpful! 🙏 And I'm glad you like the intro - I'm sending nothing but good vibes your way 😎 lol

@@Eat_Pi Thanks I'll take all that I can get

lol well I'm glad it made sense! 😃

That's a great question! As far as I know, although they share a common name, there is no relation between a secant of a circle and a secant in trigonometry

@@Eat_Pi Thank you. I should have referenced cosine rather than sine, but I assume the answer is the same. That's interesting because etymology-wise something is getting cut in both cases. But it appears secant is just a descriptor and not a relator.

@@jonwill I knew what you meant lol but yes it's probably not the easiest thing to distinguish since they have the exact same name. It doesn't help that geometry and trig get taught around the same time in school either - further providing confusion. This is why it's also important how we word things when we're talking about math, which I'm still always working on myself btw 😅

Oh wow that's so amazing to hear! Thank you for the support, I hope you continue to find the topics helpful 🙏

Thank you! I'm glad to hear it made sense 😄

What's the #1 type of math to study for ged

LMAO well good luck with your tests! 😄 I hadn't thought of making a GED math review video (no one has ever asked) but I probably will now. In the meantime I'm pretty sure I've covered most, if not all, the topics you'd find on the math portion of the GED. I can try to put together a playlist if you'd like. Also I never knew about that ASVAB exam so thanks for bringing it to my attention, I'll try to do a little more research on it and try to make a video for that too soon 👍

I try to simplify math topics as much as possible so I'm glad it made sense! 😄

You're very welcome, I'm always happy to help 🙏

You're very welcome, I'm always happy to help! 🙏

You're welcome, I'm glad it made sense! 😄

@bradleson509 Good question! When adding or subtracting, the variables stay the same. When multiplying or dividing, the variables and exponents can change. Here, we're adding. So it's kind of like saying, what's 5 apples + 7 apples? 12 apples Not 12 apples² However, when you're multiplying, then yes you need to multiply the numbers AND the variables so: 5x*7x The numbers: 5*7=35 The variables: x*x=x² So combined = 35x² Hope that helps 👍

@@Eat_Pi ohhhh, okay tysm i really needed that help♥️
