In today’s post, we are going to see what the** square of a number **is. For example, let’s calculate the square of 3:

We’re going to look at the square of any number, which we’ll call “n.”

**The square of the number “n” is written n ^{2} and it’s calculated by multiplying the number by itself: n x n.**

We can see that calculating the square of a number is the same thing as raising it to the power of 2. So, why do we call it the square of a number? We’ll explain with an example using the number 3:

In other words, **when we calculate the square of any given number (n), we are finding out the area of a square with the side length of n.**

### Some Squares

It’s helpful to know some of the more frequently used squares by memory.

Do you know your multiplication tables? If so, it’ll be a breeze for you to learn the first few squares:

**0**^{2}= 0 x 0 = 0**1**^{2}= 1 x 1 = 1**2**^{2}= 2 x 2 = 4**3**^{2}= 3 x 3 = 9**4**^{2}= 4 x 4 = 16**5**^{2}= 5 x 5 = 25**6**^{2}= 6 x 6 = 36**7**^{2}= 7 x 7 = 49**8**^{2}= 8 x 8 = 64**9**^{2}= 9 x 9 = 81**10**^{2}= 10 x 10 = 100

It’s really helpful to know the squares of the numbers up to 15 by memory. Here you go:

**11**^{2}= 11 x 11 = 121**12**^{2}= 12 x 12 = 144**13**^{2}= 13 x 13 = 169**14**^{2}= 14 x 14 = 196**15**^{2}= 15 x 15 = 225
