There's a mental math trick so that you can easily square any number ending in 5. Here's how the trick works.
Look at the first digit of 35, which is the number 3. We add one to that number, 4, and then multiply those two numbers together. So we have 3x4 = 12, and these are the leading digits of the answer.
Now we just write 25 as the last two digits, so we get 1225. And that's it! We have calculated 35 squared is 1,225 in an amazingly simple way!

not only mental math tricks, but their explanations too!
By Maurizio Codogno
Have you ever looked at people seemingly able to perform arithmetical operations quicklier than your digiting the numbers on your pocket computer? Would you like to perform similar stunts? Then, this book is for you!
Some numeric feats depend on rote learning a lot of data, but other ones are much easier to perform with just a little training: Presh Talwalkar presents a lot of them, all of which are manageable for an average person. I particularly liked the multiplication of two numbers near 200, 300, ... and the division by 19. The nice thing is that *every* trick is presented with its mathematical explanation, so that the mistery of magic vanishes... but only for the initiati!

Overall very good
By Amazon Customer
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.
