What is a seemingly simple math tool or technique that has proven enormously useful to you? We asked around the office to get our employees' opinions:
Tori: Her initial disdain for the Unit Circle has evolved into love. She remembers learning about it in 10th grade Pre-Calculus, and wondering why she would ever need it. Today, Tori is so glad for her teacher's regular unit circle quizzes- she's referenced her (completely memorized) mental unit circle countless times in university math classes.
Adam: As the Center of Math's top business guy, Adam has to say Microsoft Excel. He also brought up a second math trick: the tipping trick to determine 20% of your bill. If your total comes to $34.50, move the decimal over one place to get $3.45 (which is 10%) and multiply that by 2 to get $6.90, a precise 20% tip.
Have any other tools, tricks, or techniques to make math easier? Let us know what you think in the comments.
