Alright I will teach you though, Ok so look at the numbers on the Web 2.0 calculator, There should be +- sign right under the number 2, Ok the sign will be A + on top of a - sign, If your trying to a number Negative or Positive, Hit the number you want to make positive or negative then click the +- sign and if you click it one it will make it negative, if you click it twice it will go back to positive.
