### Multiplication, division, laser TVs, logs.

Well today I hopefully have something for everybody.

- The site DoubleDivision.org shows you an alternative long division algorithm, which takes the guessing away from estimating how many times the divisor goes into what needs divided. Also called 1-2-4-8 division.

This is a pretty cool way of dividing! The interactive tool shows you the steps right there for any problem you might come up with. - At MathLogarithms.com you can download an ebook by Dan Umbarger explaining logarithm how's, why's, and wherefore's in all detail for students.

Great resource for precalculus students. - You might also enjoy an alternative way to multiply called lattice multiplication. I did! It seems pretty simple.
- And lastly, if the math topics didn't interest you, how about my hubby's newest website called Laser-TVs.net ... It's about a totally new way of making TVs using lasers.

In playing around, I typed in "math" and came across your site. Lots of your entries seem to be people needing worksheets for homeschooling... so...

you might want to take a look at my site.

I'm putting an entire high school mathematics curriculum online, using MathML (MATH Markup Language) and Javascript to create randomly-generated, correctly-displayed math problems. Students can practice to their heart's content... different problems every time. They can print out randomly-generated worksheets + solutions (a different worksheet every time you click) for practice away from the computer (or for quizzes and so on). It's all totally FREE. (I'm a MathML Evangelist... one of the purposes of the site is to spread the word about MathML.)

I have thousands of users around the world. Because MathML isn't well supported yet, the downside is that you need a PC (not a MAC), Internet Explorer 6 (or above) with MathPlayer installed (free and easy, links on site).

Hopefully this can be of use to some of your home-schooling members. And (even more hopefully) some of them will get interested in using MathML + Javascript to create similar web exercises of their own!

Please feel free to have anyone contact me with questions about my site... I always like to know who is using it... and how, if it's working well for them... and so on.

Have a great day!
