Doing Simple Math in Your Head pdf epub mobi txt 電子書 下載 2024
Almost all adults suffer a little maths anxiety, especially when it comes to everyday problems they think they should be able to work out in their heads. No one learns how to do these mental calculations in school, where the emphasis is on paper-and-pencil techniques. With no math background required and no long list of rules to memorise, this book teaches average adults how to simplify their math problems, provides ample real-life practice problems and solutions, and gives grown-ups the necessary background in basic arithmetic to handle everyday problems quickly.
