Document Summary

People on earth: 7. 2 billion and growing! (10 billion if we were to round) What is ten billion written out: 10,000,000,000. How many stars are there in the galaxy: 200 billion, and if it was written out: 200,000,000,000. What is the distance to the nearest star (besides the sun): 39,900,000,000 km. Multiplying powers of ten e. g. 100 x 1,000 = 100,000. Multiplying powers of ten e. g. 100 x 1,000 = 100,000 e. g. 100 = 10x10 = (cid:883)(cid:882)(cid:2870) Multiplying powers of ten e. g. 100 x 1,000 = 100,000 e. g. 100 = 10x10 = (cid:883)(cid:882)(cid:2870) e. g. 10,000 = 10x10x10x10 = (cid:883)(cid:882)(cid:2872) Multiplying powers of ten e. g. 100 x 1,000 = 100,000 e. g. 100 = 10x10 = (cid:883)(cid:882)(cid:2870) e. g. 10,000 = 10x10x10x10 = (cid:883)(cid:882)(cid:2872) e. g. 10 billion = (cid:883)(cid:882)(cid:2869)(cid:2868) Rule: (cid:883)(cid:882)(cid:3028) x (cid:883)(cid:882)(cid:3029)= (cid:883)(cid:882)(cid:3028)+(cid:3029) e. g. 100,000 10,000 = 10 (cid:883)(cid:882)(cid:2873) (cid:883)(cid:882)(cid:2872) = (cid:883)(cid:882)(cid:2869)=(cid:883)(cid:882) What is (cid:883)(cid:882)(cid:2868)? (cid:2869)(cid:2868)(cid:2869)(cid:2868) = 1 (cid:2869)(cid:2868)1(cid:2869)(cid:2868)1 = 1 (cid:883)(cid:882)(cid:2869) (cid:2869) = 1.
