What did I learn this week?

This week, I learned how to understand and use Scientific Notation. Scientific Notation is a way of expressing numbers that are too large or too small to be written in a form of decimal.

For example, if the number is really long, you can make it shorter by using scientific notation. If the number is 240 000 000, we will count all the zero’s including the number after the very first number and we will turn that amount into an exponent on top of the 10. The answer would be 2.4 x 10⁸.

We also learned how to turn scientific notation into standard form. For example, when it is scientific notation, we will look at the exponent number that is on top of the 10 then turn it into zero’s. If the number is  2.4 x 10¹²  we will take the amount of exponents and turn them into zero’s. Then the 2.4 will turn into 2,4 and then we add all the zero’s. The answer would be 2,4 00, 000, 000, 000.
