You don't need a calculator for this and can use this trick to solve your problem .
I learned this trick few years back and now i am sharing it with all of you.

Maybe many of you might already know about the trick but still here i am with the trick to solve a square of number ending with 5.
example : 5 , 15 , 25 , 35 , . . . . . . . !

For example let us take 95 and see how can we find it's square without a calculator in few seconds.

Step 1) Multiply 5 multiply 5 that gives us 25.

Step 2) Now our number was 95 so we have to multiply 9 with a number that comes after it , i.e 9 multiply by 10 . ( It is 90 )

Step 3) we just write the result obtained together but first we write the result of step 2 and then step 1. So the answer is 9025.

Below is images where i have solved the question on notebook and also shown another example of it.

here we have found the square of 95
