The Best Mental Math Tricks

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.

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.

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.

Save your money.

If you like to show off with some nice math knowledge, this book is a good start!

nice

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.

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.

Easy to understand. Will greatly improve your mental arithmetic.

Brilliant book especially as I love algebra

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.

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

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.
