If you want square of any number which ends with 5 for 2 digit then
Example:
(25) ²= 625
Multiple last digit by itself which is 5x5=25
Then multiply the first digit by its next number like 2x3=6
So answer will be 625
Another example

Mastering Simple Calculations, my way!
Deleted
Did you ever wonder how you can master simple calculations?
37 + 49?
let's add 3 to 37 making it 40 and then subtracting 3 from 49 making it 46. Here it is 46 + 40 = 86 which is same as 37 + 49 = 86.
My method is called rounding and easing, I developed this method after experiencing Abacus, Vedic Mathematics.
Similarly, If I need to multiply 15 times 13? I split it into (15 x 10) + (15 x 3) making it 150 + 45 = 195.
There are many such simple calculations and various methods of making MATHS simple.

Numbers - Natural /Counting, Whole, Integers Explained!
Natural Numbers = Counting Numbers
N = {1, 2, 3, 4, 5,… infinity}
Natural numbers are counting numbers.
These are a set of numbers.
(Set = related items)
What are Whole Numbers?
W = {0, 1, 2, 3, 4, 5,… infinity}
W = zero + Natural Numbers
What are Integers?
Z = {-infinity, … -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5,… infinity}
Decimals, fractions are not part of Integers.
