Kylee and Alexa in Mrs. Brights period 6 wanted to know how many germs were around the classroom. Step 1: First write out the number. Which in this case would be: 4,560,000,000,000 Step 2: move the decimal to the left until you get a number inbetween 1 and 10. Step 3: Once you count how many times you moved the decimal, you put the number of times as an exponent of 10 In this case it would be 10^11. Step 4: write out the equation our equation

4.56 x 10^11 :) Alexa's uncle told us that there are 986,000,000 germs on a pencil, 2,580,000,000 on a book, 67,580,000 germs on a notebook, 97,863,000,000,000 germs on a chair and 3240000 on a piece of paper.
