  1. I messed up the bold  at least it's still visible.
     
  2. What's the formula to find the surface area of a sphere again?
     
  3. 4(pi)r^2 it's on google lol
     
  4. 2(x*23)p 9(67*4)p 34(xp-x)p (x*x) = xsquared p 124

    I forgotted how to write algebra •-•
     
  5. Yea you wrote it funny  here's another math joke (kinda)

    Does anyone else know how to do something but not have a clue why it works  that's how this guy is but I'm not convinced that he knows how to do what he's talking about either. I think they say "in math, you don't learn things. You learn to accept things." So if you have something memorized but can't explain it then that is fine 
     
  6. Can someone teach me how to do standard deviation cause my teacher just sits on her lazy ass and eats hot pockets
     
  7. Standard deviation is easy to find out if you have a graphics calculator... 
     
  8. I had to do standard deviation for a physics lab and my physics TA wouldn't explain it to me  I haven't covered it in math yet still. I was able to figure it out from google. I'll send you the steps that I followed from e-how, it should be straight forward.

    1 of 6
    Compute the mean of the data set. Do this by adding all the numbers in the data set together and dividing by the amount of pieces of data. For example, if you have added 27 numbers together, divide that total by 27. This is the mean of the data set.

    2 of 6

    Calculate the deviance of each piece of data from the mean of the data set. This is done by subtracting the total mean from each individual number.

    3 of 6

    Square each of the individual deviations.

    4 of 6

    Add these squared differences.

    5 of 6

    Divide the number you got from adding the squared differences together by one less than the data set. If there are 27 numbers, divide by 26.

    6 of 6

    Calculate the square root of the result of the previous step. The result of this calculation is the standard deviation.
     
  9. I've been failing in every Math test I've had since 2010 

    I got an F9 for my most recent Math test  5 marks out of 20 for my Maths class test and 16 marks out of 50 for my common test 
     
  10. Glenn, I might just have to post a troll face just for you. 
     
  11. Candies plus Candies equals to Candies square (CandiesCandies)
     
  12. Candies^candies?! Woah! I'm a math genius too! I know that 2•2=4 :)D) No seriously I suck at math and I'm jealous of the math genius. But I'm good to do other stuff that math genius are bad. YAY!!!!!
     
  13. Candies^candies is the best because it grows faster than candies! (factorial), candies^3, sin(candies) and most things.
     
  14. No one thought it was funny  I guess it was more nerdy than anything
     
  15. Pi:3.1415926535897932384626433832795028841971693993751

  16. Pie : grape,vanilla,sugar,tasty,love it, gotta have, I'm loving it, it's good mood food, crusty, brown,yummy, juicy, jelly, epic, unbelievably good, dont hate haters, opposite of Pi, in the Pi family 
     
  17. Lolz you just can't top my memory.
