Help! I first looked through the internet but nothing seemed EASY TO UNDERSTAND. Any quick ways and tips to calculate square root?! 
Im tired of using a calculator.
Do you want to calculate sqrt by hand? There is no easy and fast way to do it by hand, compared to a calculator.
Enter the base number in the calculator then press the square root symbol key.
The answer will be displayed.
+9675 I face this problem too so I memorized some of the squares of the whole numbers. Such as 282=784. But I suddenly found out that using calculator is better because......
Firstly, it is impossible to memorize sqrt of all the numbers. Numbers are infinite.
Secondly, There are fractions and decimals, I can't rely on my memory for that.
Thirdly, there are extremely big and extremely small numbers.
So after all, using calculator is the best.
