Converting between Decimal and Scientific Notation (1.5.1)

Question 1

Scientific Notation:

Answer 1

Scientific Notation 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.

Question 2

Calculator Presentation:

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.

Question 3

Numbers larger than 10:

Answer 3

Numbers larger than 10 will use positive exponents for 10 in scientific notation.

Question 4

Answer 4

Numbers including 1 and up to, but not including, 10 will use 0 for the exponent.

Question 5

Numbers less than 1:
