scientific notation
- scientific notation is used represent a very long number in a shortened way. For example 19 000 000 would become 1.9 x 10 to the power of 7
- To convert a large number into scientific notation you count how many times you would have to move the decimal over until you reach the last number.

another example but with negatives:
