I've got a math test today and im stuck on this kink of stuff

Simplify:

1)a) 2 + k x k

b) 2 x k + k

c) 2 + k + k

d) 2 x k x k

A) 2 +k^2

B) 2k+k

c) 2+2k

d) 2k^2

Right? I think.

1. a. 2 + k x k

Do the multiplication first, then add, so you get: 2 + k²

b. 2 x k + k

Do the multiplication first, then add: 2k + k = 3k

c. 2 + k + k = 2 + 2k = 2(1 + k)

d. 2 x k x k = 2k²

2 + k x k = k² + 2

2 x k + k = 3k

2 + k + k = 2k + 2

2 x k x k = 2k²

I dunno....its been a while since high school.

f*ck...I lose[/edit]

That's some easy sh*t. You just need to remember this mnemonic device, which tells you the order in which to do everything: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. PEMDAS.

So what, since you are only 13 that means you don't know what grade you are in?

You can just say what grade you are over there and people will convert it for you. Just like how they did your math for you. Lazy.

Acutally there is a new part, Parentheses, Bar, Exponents, Multiplication, Division, Addition, Subtraction.
