This book starts by explaining place value, which is about as basic as you can get. It then covers a wide range of maths topics. I found the explanations clear enough, and there are plenty of exercises or problems to solve.<br>I'm mostly reading through it to remind myself of things that have become a bit hazy over the years. Mathematics is not part of my daily life, so the knowledge will never stick well, it'll fade away again. But I'm happy to have an easy way to remind myself what maths is about.<br>If you're looking for a broad introduction to basic maths, I certainly recommend this book.<br>I don't recommend the Kindle version as some of it was more or less illegible on my ancient Kindle.<br>By the way, it has a pretty good index.
