1.5.1 Converting between Decimal and Scientific Notation

Question 1

Scientific Notation

Answer 1

• means representing a really huge or really tiny number with its significant digits shown as a number less than 10 which is multiplying with 10 to whatever power would produce the actual number. The purpose is to avoid
  having to write lots of zeroes after a number that is huge or in front of a number that is tiny.
  • Calculator presentation for scientific notation takes a shortcut because it has limited display space. It will display the
  significant digits, the symbol E, and the exponent for 10.
  • Numbers larger than 10 will use positive exponents for 10 in scientific notation.
  • Numbers including 1 and up to, but not including, 10 will use 0 for the exponent.
  • Numbers less than 1 will use negative exponents for 10 in scientific notation.
