Storyboard Text

  • Hi welcome to Trail Ridge Middle school 
  •  I heard you had a question  about Adding and subtracting with scientific notation 
  • first what is scientific notation,It is when we scientists  have a big number like 0.00000000056  and they would write it like 5.6x10^-9
  • Next how do you solve a  problem with scientific notation. well lets say you have the problem, (2.1x10^3) + (4.4 x 10^3).  
  • First you would add the constants which are (2.1 + 4.4)x 10 ^3 and when you add those you get 6.5 x 10^3.  
  • And the last thing you need to know is, if your answer is right it needs to be between 1-10.  and are answer is correct because it is between 1-10
