MindMup: Zero-friction online mind mapping The Math Dude : How to Use Percentages to Easily Calculate Tips A few articles ago, I asked if you ever found yourself at restaurants fumbling to figure out how much to tip; I guessed that you might occasionally resort to seeking advice from your “smart” phone; and I told you that you really didn’t need to. But I didn’t tell you why you didn’t need to because we first needed to cover some basics about fractions. And now that we’ve done that, it’s time to go back and talk about the power of ten percent—soon to be known as: the reason you’ll abandon your favorite tip-calculating iPhone app forever. And it doesn't stop here, because next week I'll show you how to use percentages to easily calculate sales prices in your head. What Are Percentages? Let’s start by figuring out what percentages actually are and where they come from. What Does “Percent” Mean? Now, let’s take a closer look to see where this all comes from. How to Use Money to Understand Percentages Okay, so 10% means 10/100 in fractional terms, but we also just said that 10% of $1 is a dime.

You already know, by just looking at this equation and comparing the two fractions, that x must be 5, but suppose you hadn't noticed this. x = 5 Copyright © Elizabeth Stapel 2001-2011 All Rights Reserved Verifying what we already knew, we get that x = 5. Often times, students are asked to solve proportions before they've learned how to solve rational equations, which can be a bit of a problem. To cross-multiply, you take each denominator aCROSS the "equals" sign and MULTIPLY it on the other fraction's numerator. Then you would solve the resulting linear equation by dividing through by 2. Proportions wouldn't be of much use if you only used them for reducing fractions. Consider those ducks and geese we counted back at the park. Then there are 108 geese.
Spaced repetition In the Leitner system, correctly answered cards are advanced to the next, less frequent box, while incorrectly answered cards return to the first box for more aggressive review and repetition. Spaced repetition is a learning technique that incorporates increasing intervals of time between subsequent review of previously learned material in order to exploit the psychological spacing effect. Alternative names include spaced rehearsal, expanding rehearsal, graduated intervals, repetition spacing, repetition scheduling, spaced retrieval and expanded retrieval. Research and applications The notion that spaced repetition could be used for improving learning was first proposed in the book Psychology of Study by Prof. At the time, spaced repetition learning was principally implemented via flashcard systems. There are several families of algorithms for scheduling spaced repetition: Pimsleur's graduated-interval recall Software Some implementations:
WiseMapping - Visual Thinking Evolution Speech Recognizer — Voice-to-Text in Google Chrome [Please also see my more recent post on TalkTyper, an even better Voice-to-Text option for Google Chrome.] The more I use it, the better I like Google Chrome. It is without question my preferred browser now. Speech Recognizer is a Chrome app that provides a text box for using Chrome’s built-in speech recognition to create text. After the app has been downloaded from the Web Store and installed, the icon to activate is found in the list of apps that appears when you open a new browser tab, as shown below. It could not be easier to use this voice recognition app. Text from the text box can be edited, then copied and pasted anywhere.
