Despite that, this is another great book in the Fred series. Math is getting serious here for both the parent and the student. If you as a parent don't have a strong math background you might be intimidated by the content of this book. The nice thing, though, is that there are 5 chapters that review beginning algebra concepts so those really help to refresh your student's (and your own) memory.
Some of the new concepts taught in this book include:
- ratio, proportion and variation
- radical equations
- exponential equations
- the laws of logs
- and permutations and combinations
If you have a student who is good at math and looking to advance, this is a great next step in the right direction. You can check out more about this book here.
