Scientific Notation (Sci nota) 

Definition
is a way to express very big or small numbers place the decimal point so that there is one nonzero digit to the LEFT of the decimal point write the remaining sig figs count the number of places the decimal point has moved from the original number  this will be your exponent for 10  If the original number was less than one its now negative  if the original number was one or greater its positive
EX: 289,000 2.898 it moved 8 places 2.898 x 10 (8) *the 8 is the exponent* 


Term

Definition
 simply move the decimal point to the RIGHT for a positive exponent of 10  move the decimal point to the LEFT for a negative exponent of ten  use zeros to fill in the places
EX: 5.093 x 10 (6) 5,093,000
1.976 x 10 (4) .0001976 


Term
adding and subtracting sci nota 

Definition
 add or subtract the base numbers then put the given exponent on the 10
EX: 2.56 x 10 (3) + 6.964 x 10 (3) 2.56 + 6.964 9.52 x 10 (3)
