One thing I learned this week was scientific notation, scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.

when you have a big number with a lot of zeros, you move the decimal places until you reach the big number and put the important number as a decimal and when it is all zeros, you do the decimal number times 10 and however many decimal places you move it, that will be your exponent.
