A ponderous tome, containing information in an encrypted form of english. Supposedly teaches how to do math, but incomprehensible to anyone who cannot already do math (See catch 22). Often, the number of Greek letters and obscure symbols found within outnumber the actual english words. Enjoyed by no one. Any exceptions lie.
After hours of studying his math book, he understood no math.

A Pi-Free Math Book 

The mathematical equivalent of a meeting-free day or passport-less travel. When the sight of the symbol π is enough to trigger panic or paranoia among billions of folks worldwide, who think they weren’t born or blessed with the “math gene.”
Just as a math book without equations or formulas could raise the sales figures by a few folds, a pi-free math book could give thousands of math-anxious folks more confidence in picking up a pop math book without feeling unduly stressed.

Singapore Math Books

Math titles that marry decent quality with affordability—authors must be racially, religiously, and sexually sensitive, while the Ministry of Education (MOE) controls the price of the books.
Because Singapore math books cost a fraction of their American counterparts, US distributors have been importing them for homeschoolers, who think they're getting value-for-money textbooks—a number of them might even mistake Singapore for a city in China.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.

Me: Woah! TLDU!
