What dose it mean when a item is squared and how do you caculate it?

Question

I was not paying attention to math class coding is honestly harder than I thought and I hate math so help me out

Answer 1

I guess it's a valid question, so...

To square a number means to multiply it by itself, so "x squared" equals x*x. The naming is probably linked to the fact that this is how you get the area of a square, given its side of x length. Similarly, "x cubed" is x*x*x, as this is how you get the volume of a cube with a side x.

Example:
3 squared is 3*3 = 9
4 squared is 4*4 = 16
2 cubed is 2*2*2 = 8

Answer 2

@Pouch, chill mate, so your question is regarding the squared as in [a, b, c] or (a + b +c) please give a little more about it, I'm afraid I'm not getting your intention here :)

Answer 3

If you meant () parentheses in arithmetic operations it generally means that whatever calculation within the parentheses are calculated first, prior to other operations.

e.g. 2 * (5 + 3), here, 5+3 is calculated first, then the result will be multiplied by 2.

Hope I get your question correctly.

Hth, cmiiw

Answer 4

I just want to learn how to code and you treat me like s***
