\"Flat<\/a><\/p>\n<\/td>\n

\n

Flatworld Knowledge has an interesting approach. They offer "Premium open textbooks by top authors. Fully editable, Totally free."<\/p>\n

You can view the books at no cost, while there are pay options for printing or eBook versions (iPad, Kindle, etc). It's worth a look. <\/p>\n

(Only elementary algebra in the math section for now - more to come. They also have business, economics, and science books. Look for the "Read free now" button.)<\/p>\n

4. Math tip: Understanding math formulas<\/h2>\n

Suitable for: <\/strong>Everyone - especially those with exams coming up. <\/p>\n\n\n

5. Is there a place for invention in math?<\/h2>\n

Suitable for: <\/strong>Everyone.<\/p>\n\n\n\n
\"Learning<\/a><\/td>\n\n

Little kids invent things all the time. Should we let them (and their older siblings) invent math?<\/p>\n

7. Final thought \u2013 perseverance <\/h2>\n

It's very easy to get stressed while doing math. How often have you screamed "I give up!" when doing math homework?<\/p>\n

The Japanese have a great saying that all math students should remember, especially when feeling frustrated: <\/p>\n

\n

Fall seven times, stand up eight. [Japanese proverb]<\/p>\n<\/blockquote>\n

In Japanese, we say this as "Nana korobi yaoki<\/em>" and write:<\/p>\n

\"nana-korobi-yaoki\"<\/p>\n

The first character is nana<\/em> (the number 7) and the 3rd character is ha<\/em> (the number 8). <\/p>\n

Until next time, enjoy whatever you learn. <\/p>\n
