A free math website that explains math in a simple way, and includes lots of examples! Includes Elementary Math, Pre-Algebra, Algebra, Pre-Calculus, Trig, and Calculus.

This website is a treasure to find! I have already referred my students to it. I see you are working on Geometry. I great rescource for Geometry (including animations on constructions with a compass!) can be found at http://www.mathopenref.com/

I don’t yet have a twitter account – noticed that the name shelovesmath is taken π I think I’ll create one though – have to think of another name. Thanks for writing! Lisa

Wow! This website is such a great help to teachers and students and I just discovered it today! Thank you so much Ms Johnson! Can you recommend projects that go with some Pre-Algebra and Algebra1 lessons too? I would greatly appreciate it π More power to you!

Thanks so much for writing! Did you see my Pre-Algebra and Algebra 1 pages? I have various story problems, etc. What did you mean by “projects” – and I can see if I can help more π Lisa

I was looking for a simple parent function and came across this site. I know you say this in the description:
“In no way am I insinuating with this web site that girls are worse in math than boys. I just believe that math examples need to be more geared towards girls, and math should be taught more simply for both girls and boys! I donβt have a problem with boys reading this site, since, for years and years, girls have been reading boysβ math textbooks.”
However, I find this site somewhat offensive. It’s good you don’t think girls are worse in math, but how are math examples not geared toward girls? There are issues in our society because people do think boys have more mathematical or logical brains, but how is teaching math in a more “girly” way helpful? And you said you liked prettier things and I can see that by the attractive purple lettering. That’s nice, but when I’m doing my homework, I don’t need to make the information pretty. Girls just want to learn the material, like boys. This seems to have good intentions but is very sexist, especially with the opening site advertising your easy to understand examples and how you will make math make sense. Thank goodness — without you and the pretty lettering, my fragile mind would be too grossed out by most math to be able just to LEARN the material!

Thanks so much for writing. You raise very good points, and actually this is something I’ve been struggling with lately. The web site started out when I was tutoring a some kids and they thought I had good ways to explain things and good examples (and they just happened to be girls). So I took the slant to make it look more “girlish” and even first called it “GirlyMath”. But I can see how some can perceive it be sexist and I’ve actually been considering changing the name and making it more generic, since it’s gotten so popular. (I just want to try to finish the site at this point, and then consider changing the name and color scheme). But I’m truly sorry if I offended you in any way; I agree that girls or anyone for that matter don’t need “pretty” explanations of how to do math. And it was certainly NOT my intention to exacerbate the issues in our society where boys are perceived to have more logical brains. Thanks again for your valuable feedback. Lisa

I like She Loves Math by its content and style. I would like to post a few math articles on She Loves Math. Please advise me on how to do it.

Donna,
Thanks for writing!
Yes – I tutor a lot of Geometry and it’s on my list of topics to write about; I just need to finish Pre-Calc and Calc first π
Let me know if you have any other suggestions!
Lisa

I was struggling particularly with conic sections and happened upon your site, and I have to say that you offer some of the clearest explanations that I have EVER found. Very helpful material, thank you very much!

Ryan,
Thanks so much for writing!! Comments like yours make me want to keep writing and finish the site! Let me know if you see any things that would make it better. Thanks again, Lisa

Thank you for this great help! I am looking for help with Permutations, Combinations and Binomial Theorem (Pascal’s Triangle). Is there anything here on that? Thank you.

Kelly- Thanks so much for writing – please spread the word about She Loves Math, and also let me know if you have any suggestions! Comments like yours make me want to keep writing more and more π Lisa

Hello Madam Lisa your website is so helpful for a student just like me. Thanks for the replying the comments with some problems involving math. God bless you. I hope you continue helping students. Love from the Philippines π

I currently am studying for the TEXES 235 exam and came across this document http://www.planotutor.com/images/Domain%201.pdf which was extremely helpful. I was wondering if you created any additional documents for the other competencies. Your site is very very helpful as well!
Thanks in advance π

Hello and thanks for writing! Gosh, I wrote that document so long ago, and I don’t have other competencies for the TEXES exam. I can write them up if you think that would be something useful; most of the information is on my She Loves Math website. I found other TEXES books out there, so I didn’t think there was a big need to write more π Thanks for using She Loves Math! Lisa

One thing I am having hard time explaining is ‘negative times negative is positive’. Does someone have a real life example that can be used to explain this concept?

I don’t know how I only found this website JUST NOW. I’ve been struggling with the math in my pre-calculus and trigonometry classes and its almost explained better here than it is in class. I need to take math up to calculus II and I’m so happy to have this as a resource. THANK YOU!

Thank you so much for your kind words! Comments like these make me want to keep working on the site and finish! Please spread the word about She Loves Math, and like my facebook page, if you don’t mind π Lisa

THANK YOU so much! I was looking for a useful chart of all the conics, and I found your site. Thank you for helping make this math teacher’s life easier today. I appreciate your time and your effort very much. I LOVE MATH too!

Thanks so much for writing! This makes me want to write faster and finish the site π Please let me know how I can make it better.
And please spread the word about SheLovesMath.com π Lisa

Love your site! It’s going on my syllabus for next semester.
But I found an error on the Limits and Continuity page. Under the heading of Continuity of Functions, you have the coordinates of the hole as (2, 0). This is incorrect, the hole is at (3, 1). Also, you might include in your discussion how one can see this hole on the graph if one uses Zoom 4:ZDecimal on a TI 83/84 calculator (although one has to turn the axes off to see it on your next example)

Mary,
THANKS so much for finding this error – I did that part a little too quickly π Please let me know if you find anything else. I’m trying to get my husband to edit the webpage, but the math is getting a little too much for him – haha.
Thanks again,
Lisa

Hi
If you compile the whole contents and make a hard copy-that will be a very useful book for students and teachers both.And you will be known as a great author of the time.
Great works!!
Just keep it up.
Brij Kumar

Thank you so so much for the kind words! I plan to keep working on it to make it better, and then make a book. Please spread the word about SheLovesMath.com! Thanks again – you made my day π Lisa

Outside of the “pink” color, I don’t see your site as being girly. In fact, had you not mentioned the reason for starting the site, I would have presumed you liked pink–that you found the pink to be soft and soothing, taking the panic out of the math!

As for the simplicity of your site versus the text books, I think that is the key! Text books make things seem so difficult! I read a textbook passage to my students (I don’t remember the passage or topic–just its effects on my class). Looking up, I saw the disconnect and discouraged looks on my students’ faces. Seeing this, I said, “Wow! That sounds complicated … nearly impossible to do! Then again, maybe it is impossible.” My students began breathing sighs of relief as they nodded their heads and commented in agreement. (They were relieved that I recognized the difficulty in what I had read and that I didn’t expect them to find it easy.) Then I re-read the passage, bit by bit. We decided it would be complicated and difficult but doable. Then I restated the passage–in easy to understand terms. The looks on my students’ faces was priceless! I then received comments like, “Why didn’t they say that in the first place? Is that all they wanted us to do?”

You write using math terms but in everyday language…thus the “simplicity” not found in most textbooks.

Thank you for creating this site and sharing it with the rest of us–teachers and students alike! Thank you for helping me help my students!

Terrie,
Thank you SO much for your kind words – that means so much to me! Yeah, I go back and forth on the issue of “pink” on the site (and name), but think I will keep it for now. I think my language on the site reflects my 13+ years of tutoring match – knowing what trips kids up and what makes math more clear.

Please keep using the site and let me know if you see anything that can be done better π
Thanks again,
Lisa

I just wanted to let you know how useful I think this site is. It is comprehensive, easy to use, and highly impressive. Major props to you for finding the time to create such a fantastic resource.
I have a recommendation for your Calculus tab: I’ve found that many calculus students don’t necessarily have trouble understanding the calculus so much as remembering the algebraic properties and rules they need to finish solving problems. I think making a quick guide to algebraic properties and rules for students who don’t need much explanation about algebra–i.e. calculus and higher level math students–could be very useful.
Just a thought though! My main reason for writing was to let you know how impressed I am with this site. Keep up the great work!
p.s. love the site name, I don’t find it offensive. In fact, I think it may encourage younger girls to explore and pursue STEM careers

Cristina,
Thanks so much for writing, and I love your suggestion! I go back and forth with the name and the “pink”, but I think I will keep it for now.
