I liked marticies better
But I've taken linear algebra so row-echelon form at this point is nice and easy.
Now for more complicated matricies, its another story

see I'm not sure what to do in my future
since I'm taking pre-calc freshman year, I'll be done with BC junior year my mom wants me to take multi-variable calc in senior year but I want to take linear algebra or like differntial equations not more calc

Well, I was doing my teaching internship but that's in the trash now. I'm so used to doing online classes they don't phase me but most of my instructors follow similar syllabuses so I feel like I'm doing the exact same thing but with a different topic from each class. I'm just ready to graduate, periodt.

so 3 x 4 = 12 divided by 2 = 6 - 3 = 3 + 5 x 3 = 15 divided by 3 = 5 so 3+5=8!

Exactly

If you want to know some tricks to make multiplying fractions even easier, you can do what's called cross canceling. This works when you have the same number in one of the numerators and denominators.

Example:

See how I got rid of a 2 in the numerator and denominator? That's because you can essentially rewrite the fractions in any order because order doesn't matter when multiplying. So therefore, you can rewrite it as 1/3*2/2 instead of 1/2*2/3. 2/2 is 1, so it would give you 1/3*1, which you can easily see is 1/3. For smaller fractions it doesn't matter much, but later on this will be very helpful once you start dealing with very large functions involving fractions.

And to add onto that, you can do it when the numbers are different but are factors of each other, also by rewriting the fractions to make them easier.

Here's an example:

See how I rewrote 4 as 2*2? This allowed me to use cross canceling again to simplify the fraction and make it easier to solve.

For the example you posted you can actually use cross canceling for both fractions. Do you want to try it? It's going to be super useful in the future, it'll practically save your life.

Tbh multivariable calc is better to start with than differential equations or linear algebra. Although you can get by in both without multivariable calc. But then again, in the future you might need it anyways so you'll have to take it later anyways, so if you look on the bright side you'll be completely done with calculus by senior year and never need to take it again unless you plan on going into a math heavy field,then you might need to take vector calculus. But for most engineering disciplines it'll be more than enough calculus once you finish multivariable calc.

That's a mood, except I feel to dumb to graduate so far What are you studying? Education?

 

[kinnie]

You are so not dumb. If anything I'm the one in need of more brain cells because I seem to be lacking. lol
Yee, I'm studying to teach K-6. I'm currently enrolled at a community college and I'm graduating in May.
Then I've gotta transfer to uni for my bachelor's. It doesn't hurt to earn a higher salary PLUS I plan on teaching
abroad anyways and it's required. What are you studying?

Dang, k-6 you're brave Where do you want to teach?

I'm studying mechanical engineering and I'm trying to focus on robotics because I want to work on biomedical robots once I graduate.

 

[daesuki]

I like my creative writing class. Math is confusing I hate it

Hmm...I haven't decided yet. Although South Korea does sound hella tempting.
There's a lot of benefits that come with teaching abroad that I like too.
That's so cool! What made you interested?

Honestly I'm interested in almost everything science and engineering related. Like recently I've been super interested in virology, before that astrophysics, before that archeology and paleontology at some point, not to mention biomedical engineering, also manufacturing is awesome and that's just a small sample there's many more

But I've been into robotics since high school when I was on a robotics team. I love physics and manufacturing and I like how they work together with electrical and computer engineering. And since biomedical robotics is something that is is exploding right now and since Im interested in biology and anatomy, as well as diseases and surgery, especially of people, it's all just perfect.

It's true lmao I'm missing my primary school math

so you're saying I'm wrong
I want to do something with chemical engineering in the future lmao so hopefully I'm done

Thank you so much, thanks to you i finished the lesson alive

190
Youre not from New England so Im less worried but please don't hate us

Thank you so much, thanks to you i finished the lesson alive

Yay!
Always glad to help

If you'll be in Chem Eng then higher level calc will be useful. But if you want to go into Chemistry then linear algebra will be more useful.

Ooooh. FRC Team 190 is legendary.

I was an FLL (FIRST Lego League) coach for a few years.

Replace a with 1 in the equation and b with 3, then find the answer

For example, if you had 3x+8y-5 when x=2 and y=6 it would be
(3)(2)+(8)(6)-6
6+48-6
and the answer is 48

Whenever you have variables and you know what the value of them is you can just replace them with the value thats given

Now explain the quadratic equation

Just kidding 🤣
