I'm almost 26 years old and working an overnight security guard job and wanting to do more with my life. I didn't fit in with how things were taught when I was in school, and dropped out of high school. I was homeschooled from 6th to 8th grade so when I came back to the public school district they threw me into algebra 1, and unsurprisingly, I failed it 3 times. Now here I am again, learning on my terms, and so thankful that this free resource exists. Like Galileo said, "Mathematics is the language with which God wrote the Universe." It belongs to all of us and I'm proud of anyone else here trying to learn even if it isn't intuitive to them. Keep going!
I did the same thing when i was 27, and now im 34, a programmer. So grateful for generous people sharing knowledge. And I wish you all the best. 💪Learning is enjoyable.
are we the same? im 25 working overnight security shifts, learning this stuff, was never good at math besides basic math, no matter how hard I tried, haven't touched this subject in seven years (was in the army) and now I feel like I have to play catch up again.
my son is 10 and has currently know most of algebra complicated and basic, we want him to watch your algebra vids from basic to complicated so he doesn't forget this very useful math
Yes, but a lot of people don’t like that because what’s the point of a TEACHER then? Just go home and watch videos. And plus, going to school is fun with friends, and an actual fun teacher.
I have just found your channel and you're a very good teacher... Even though this topic is not what I find very hard as I'm already more advance. I look forward seeing the subjects I'm seeing in my Maths class right now. Thank you very much for the lessons, they are greatly appreciated and I think I'm speaking for everyone else here :)
Hi Sir, I just want to point out at 05:40, -2³ is not the same as -2 * -2 * -2. Since it was not on parenthesis, just so not to confuse others. Thanks for being my teacher. Please keep it up!
Hi Oscar, I know the rules and jargon can get confusing! When a number has a minus sign by itself, it is a negative number. I can see why it might be easier for a beginner to evaluate expressions such as -2 with parentheses around the expression so that it's clearer, but it isn't necessary and Khan wasn't wrong to omit them. Infact, you'll probably never see it the other way for an expression like that, just because the minus sign must belong to the 2 and it must be the same as (-2)³. You also don't need parentheses between -2*-2*-2 because it doesn't matter what order you do the multiplication in since they're all -2.
You've got to put the -2 in scopes to emphasize that the power of three acts upon both the minus and the two, even though both options result in the same answer in this case.
Danielle Assadourian depends on your question. They are infinite many solutions to those variables if your talking about the solution set for that equation.
My teacher gave my class 1 hour lecture on this but no one had any idea on what she was talking about, later she gave up and stared searching for an example. After watching this everyone finally understood. #thisiswhywedontneedteachers
Can there please be a post on just Inequalities, and on the units ahead of inequalities in the basic High School Algebra 1 Glencoe Mathematics Textbook? Having some trouble in Algebra in terms of actually absorbing material in class, it's as if I just go into Day dream mode automaticly
Life hasn't been good I've been lacking motivation. I realized if I want things to get done I gotta do it no procrastination. Plus you make learning fun especially when you ask us to solve it. It's fun when I get the answer. I'm gonna make my siblings watch it with me too lol. Have a good day, Khan

so i have a question; if you had, for example,
x + y + z = 5 but you weren't given the values of any of the variables, what would you do?

The equation would not be false. That's when you put in your own numbers. Some examples are: 1+2+2=5, 2+3+0=5, or 5+0+0=5.

as long as you dont define that your variable can only be one type of numbers yes
