# FAQ: How To Do Mental Math Fast?

## How can I train my brain to calculate faster?

For easy and fast mental math calculations, you should add or subtract from the left to the right. For example, adding 340 + 215 will quickly give you the answer: 555. In case of carrying forward numbers, just add it to the digit before them, like 340 + 285 = 625.

Use subdivision to quickly calculate large numbers in your head. For example, if you have to find the result of 32 x 125, divide the first number in half and multiply the second number by two until you have an easy problem to solve (16 x 250; 8 x 500; 4 x 1000 = 4,000).

## How can I quickly subtract my mind?
