Exponents and Scientific notation

I am going to teach you about exponents. The reason you have exponents is because when you have big numbers you can use these to break it down to make it easier. For example:Instead of writing 6*6*6*6*6*6*6 you can just say six to the seventh power or 67. The 6 is called the base and the 7 is called the exponent. You might think this is pointless but in life you will use this to do different things like if someone was trying to figure out how many stars are in the sky instead of saying their are 100 billion billion or you can just say 1020.
