Scientific Notation Scientific Notation is a short-hand way of writing down really big number, or really small numbers. The mass of the earth is: Saying this number is not an easy task. Writing these zero’s is not very convenient (or fun) To help us we use Scientific Notation

Scientific Notation Numbers expressed in scientific MUST be expressed as a product of: a number greater or equal to one, but less than ten And A power of ten

Are these Numbers in Scientific Notation?

What is 561 000 000 000 in Scientific Notation?
1. Place a decimal point after the first non-zero digit(giving you a number greater or equal to 1 but less than 10) Drop the trailing zeros 5.61 Count the number of places(boinks) the decimal was moved. Express this number as an exponent of 10 5.61 x 1011
