ive made a formula for it


n^2 = ((n-1)^2 + (n + n-1))

heres an example

how do we find the square of 4 (its obviously 16, but lets pretend we dont know)

lets substitube the numbers in the formula:
4^2 = ((3)^2 + (4 + 3))

4^2 = (9 + 7)

4^2 = 16

wow isnt that cool

I tested this on another number and it works

But honestly you can multiply the number by itself

Although this could be easier for more complicated numbers

but you see

7^2=((6)^2+(7+6))
but idk 6^2
6^2=((5)^2+(6+5))
but idk 5^2
5^2=((4)^2+(5+4))
but idk 4^2
4^2=((3)^2+(4+3))
but idk 3^2
3^2=((2)^2+(3+2))
but idk 2^2
2^2=((1)^2+(2+1))
so now
2^2=(1+3)
2^2=4
so i have to go back and plug in
3^2+(4+(3+2))
and so on..
