Review: Great book and full of neat tricks to make mental maths tantalisingly easy! - Amazing book! Sat up in bed reading it now! I have an interest in maths and have been trying to sharpen up my mental skills. If you want to do this too, then this is the place to get started! The authors make the book accessible and fun, and I find myself eager to learn a new skill each day. I don't bother with calculators much anyway, but I'm getting more confident and can now square big numbers in my head and do multiplications and divisions of a greater complexity than before. In an age when everyone relies on a calculator to do 10/2, being able to bash out some answers to tough questions faster than someone can whip out their phone does impress!
Review: Handy book - Good little math tricks and tips in here. You aren't bad at math you were just taught poorly, remember that. This book makes math easier to access and become skilled at. Worth adding to your book collection, give it a try. Arthur Benjamin has some pretty cool TED talks too if you haven't seen his live stuff, he makes math look really fun as good teachers should.

### ⭐⭐⭐⭐ Encouraging results after 50 hours of study.
*by M***H on 9 December 2020*

I always wanted to get my poor mental maths up to scratch. I bought this book in lockdown and committed to reading / practising for 25 minutes every single day for four months. At the end of each month, I tested myself with a set of 20 mixed questions. Starting point: I know my times tables, but have to work my way up them for some of the higher numbers. I can do two-by-one multiplication and addition/subtraction of three-digit numbers with a bit of thought. Anything much else I can do only with considerable difficulty. Double-digit squares or three-by-two multiplication in my head is not possible. After one month: I have internalized the materials in the book. I can now do double-digit squares and three-by-two multiplication mentally, although it sometimes takes a while. Holding numbers in my head is a big problem and I frequently have to look back at the question. Test result: 16/20 in about 20 minutes. After two months: Still all rather difficult. Test result: 15/20 in about 21 minutes. Oh dear. After three months. Multiplication tables feeling a little more comfortable now, along with holding numbers in my head while performing calculations with other numbers. Test result: 14/20 in about 17 minutes. After four months. Multiplication tables feel comfortable in most cases. Mental agility seems to be coming on. Test result: 15/20 in about 12 minutes. While I won't impress anyone with such results, I am encouraged by the improvement generated by reading this book and practising its techniques. I found it far better than the Trachtenberg System, which relies on a right-to-left approach to calculation that does not really work without using paper.
