Learned Math Functions To Make Easy Calculations
Have learned new techniques and methods to for solving mathematical problems. What I have learned and practicing is fun and educational. Shared some techniques with a third grade teacher and she was excited to learn some of these methods.

Love This Book!
I'm in 6th grade, and I watch Presh Talwalkar's YouTube channel, Mind Your Decisions. I really needed some tricks to memorize all the stuff I was learning, and here it was! It had many tricks to learn, from squaring any number ending in five to easily finding percents. I just love it and would totally buy it again.

Filled with excellent "tricks" for mental math
A well written book. Contains all the mental math techniques I have used throughout my life, and MANY more. I think it's fun to read and practice. Looking forward to reading more for this author.

Overall very good
Many useful tips with examples and practice problems. Also has proofs for those inclined to delve further into the mathematics. The memorization for some tricks may outweigh their usefulness but for many others it's a reasonable trade-off. Overall, very good.

Loved it
The format is extremely clear. The author provides procedures, examples, and practice problems for each math trick. There are even proofs on why these methods worked. I found the practice problems fun because the methods were so quick and simple. This is really something I look forward to using during my life as a student.

Di facile lettura, con molti esempi.
Rispetto a libri simili letti in precedenza lo ho trovato più completo e di facile lettura con paragrafi corti e con molti esempi per ogni trick.

Good tricks
The book has good mental math tricks, though you will obviously need to practice to remember them. The style is simple.

Truques simples no geral
o livro apresenta maneiras rápidas para fazer contas (multiplicação, divisão principalmente) mas no geral são simples. o melhor truque que encontrei foi o de calcular o dia da semana para uma determinada de um ano qualquer.
