This book was a good starting place, but it wasn't really that illustrative. In trying to be easy to understand it was a bit too simplistic, at least when it came to examples. I would have appreciated the math being done in number-form, and not just explained. I learn either visually or by doing, and having verbal explanations of calculations, even when done only with round numbers, didn't really help. Additionally, it's very dry, and quite honestly, in the version I read, the font was not ideal for what is effectively a text book. I'll still ask my husband to read it, and keep it as a reference, but I'm really going to need a different presentation to make it stick.
