Scientific Notation Mrs. Rauch 11/6/15
What is the scientific notation? • In science, we often deal with very large or very small numbers, scientific notation is a way to write these numbers easily in decimal form • Often times, this means getting rid of all the zeros in the number, but not always!
How does the scientific notation work? • There are always two parts of the scientific notation 3.5 x 108 • Decimal: you should only have one number in front of the decimal point • Exponent: this expresses how many zeros are in the number and can only be in whole numbers
What does the scientific notation mean? The decimal number is your starting point. You know how many places and which way to move the decimal point depending on the exponent. 3.5 x 108 • The exponent is positive 8, which means you move the decimal point 8 places to the right • In all the empty places you add zeros, so it becomes 350,000,000 3.5 x 10-8 • The exponent is negative 8, which means you move the decimal point 8 places to the left • In all the empty places you add zeros, so it becomes 0.000000035
