More Math Problems 'cause I suck at easy math

Please answer the following because I don't trust my calculator to check my stupid people math answers:
Problem one: 2*3-2*6+14 divided by 7.
(the stars * are multiplication signs..also please show HOW you get the answer you did so I can see where I'm screwing up.)
Problem two: 12 divided by 3*2-2 (the last number in the equation is supposed to be 2 to the third power)
Problem 3: (-3+9) Note: The nine is supposed to be nine to the second power
Note: There's supposed to be a line like there is in a fraction under the (-3+9 to the second power) and there's supposed to be a 4 under it so it's like a fraction but my computer wont do that......lol I'm horrible at this

you can denote exponents by using ^ . use the PEMDAS rule. and when you have multiplication vs division, go from left to right of the equation. same goes with addition vs subtraction. once you get through paranthesis and exponents in the equation (if you have them), do the remaining steps left to right.

1) 2*3-2*6+14 divided by 7
=6-12 + 14 divided by 7
= 6-12 + 2
= -4

2) 12 divided by 3*2-2^3
=12 divided by 3*2-8
= 4*2-8
= 8-8
=0.

3) (-3+9^2) / 4
= (-3+81) / 4
= (78) /4
= 39/2 this is in fraction form; otherwise, in decimal form it's
= 19.5

Just follow the order of operations, first do insides of parentheses, followed by exponents, then multiply, followed by division, addition, and subtraction. As long as you do your calculations in that order, you should be fine.
