Scientific Notation

4000=4x10^3

Scientific notation is just a way of writing a very small or very large number in shorthand. This form of writing number makes it easier to read and is less characters.

For example; the number 89000000000000 can also be written like 8.9 * 10^13

for smaller numbers like 0.000000000000009 can be written like 9 * 10^-15

Notice that when it is a smaller number the exponent is negative, that is because the decimal is moving to the right. When the exponent is positive, the decimal moves to the left.

Note: * means multiply.
