Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

Krista, you make math so easily approachable and don't try to sell it off as if it's impossible to understand.  The best part about your videos is that you're engaging, fun and not monotonic.  Fantastic work :)

You girl helped me pass the calc final in my university. I'm studying math and can't imagine calc without you. Thanks, respect and best wishes to you.

I have spend the last 4 months watching probably every YouTube video you created. And it has paid off! I found out today that I not only passed business calculus . . .but I got an A. I am giving you 95% of the credit. Thank you for sharing what you know. You are amazing!

[SawdustAndThings]

You know I'm a big math nerd. I took up through calculus four in college and I've never met/seen anyone that can explain calculus as well as you just have in this videos and others I have seen you in. I'm flabbergasted! You not only have an extroardinary understanding of the subjects at hand but know how to relate them to others so that they may learn the world of math. Outstanding! Keep up the good work! I wish you made these back when I was taking these classes.

Thank you!

Back in college after a decade away from school and needed a quick refresher on my basic calculus. You explain everything very clearly without getting bogged down in minutae. Totally worth a subscribe!

[kristakingmath]

I'm really glad you like my videos! If you like math, I would definitely recommend that you study calculus in your spare time! Most 13-year-olds aren't ready for calculus, so it's very impressive that you're interested at your age! Keep up the good work! :D

[dodexodus]

You managed to explain this so much better than a multitude of people i've spoken to/watched so far, thanks pretty lady! :)

[nbraceface]

You have no idea just how much you've helped you. You're the reason why I haven't quit calculus. THANK YOU THANK YOU THANK YOU <333

[kaylakinkead]

I can't tell you how helpful your videos for calculus have been! I used your section on derivatives for my last math exam and received my first A on a math test. Thank you so much, your tutoring videos are amazing!

[johnhilliard]

I think you have great empathy! you seem to be able to anticipate what students may find difficult and so you spend time on detailed explanations, , a really great teaching technique.

[kristakingmath]

Wow, thanks for the comment! You are so welcome! I'm so glad I've been able to help. :)

[jomosoft]

Your videos look more and more professional and I can't tell you enough how helpful they are. Thanks for yor efforts !

[navee]

You are such a great teacher! Thank you for taking your time to make these videos, they're very helpful and much appreciated!

[jakeshaker]

Not the usual old guy with a blurry camera. What a refreshing change of pace.

[JaredChJared]

In high school I never had a chance to take calculus because I hardly passed geometry. Now I adore math and have a second chance to learn thanks to you. Thank you for your videos and e-book Krista. I'm really grateful.

[kristakingmath]

this happens for the same reason that x^2 becomes (1/3)x^3 when you integrate it. remember that x^0 is equal to 1, so you can basically think of the 3 as 3x^0, because 3x^0=3(1)=3. if you have 3x^0, then when you integrate you get (3/1)x^1, which simplifies to 3x. it's all just power rule, but it's a little harder to tell that it's power rule when going from 3 to 3x. hope that makes more sense! :)

I really like your lectures, very visual, and by that I mean effective use of explanatory charts as well as a pretty teacher.

[abdullahsheheween]

I hope if we can see these kinda people teaching in Colleges. 6 mins video explains way better than our prof. who would take days to explain that. Thank you so much Krista for your help, you are awesome!

[kristakingmath]

Oh awesome!! I'm glad you like them! I'm trying to make them look better, and hopefully it's helping!! :D

[hermitcrabgirlsarah]

This was the easiest Calculus video to follow I've ever experienced! Thank you!
