I would say that for 80% of purposes, the Trachtenberg system is superior

but there are certain useful facets in this book as well
adding and subtraction methods
and multiplication tables

در تلاش برای نوشتن یک کتاب.

مشکل خیلی از این کتابای ریاضیات سریع اینه که انقدر روش های مختلف و پراکنده ای رو میگن که توی ذهن نمی مونه و تلاش من هم الان همینه که یه کتابی بنویسم که این مشکل رو نداشته باشه!!!

گرچه خیلی از مطالبی که گفت هم مفید بود.

call me a nerd but this was actually really interesting. It definitely introduced me to a number of clever techniques to approach basic mathematics that I never knew even existed. It was enlightening and quite worth the read especially the lessons on mental calculation which probably didn't stick too well in my head ... way too many numbers. But interesting nevertheless :)

Now that was interesting! Want to learn a new way to multiply large numbers in your head? This book will teach you if you have the will power to read this slowly and practice. I found it fun to learn, maybe you will too.
