  1. SCIENTIFIC NOTATION AN INFORMATIVE POWERPOINT BROUGHT TO YOU BY LAUREN CALVERT, HALEY DAVIS, AND DEANNA HEBERT!

  2. SIGNIFICANT FIGURES • Significant Figures in a measurement consist of all the digits known with certainty plus one final digit, which is somewhat uncertain or is estimated. • The rules of sig figs are found on page 47.

  3. SCIENTIFIC NOTATION • A method of writing or displaying numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10 • Example! • The scientific notation of 10,492 is 1.0492 × 104.

  4. ANDDD THIS IS HOW YOU DO IT! • Changing numbers from scientific notation to standard notation. • Ex.1  Change 6.03 x 107 to standard notation. • Remember,  107 = 10 x 10 x 10 x 10 x 10 x 10 x 10 = 10,000,000 • So, 6.03 x 107 = 6.03 x 10,000,000 = 60,300,000 • Answer = 60,300,000 • Instead of finding the value of the base, we can simply move the decimal seven places to the right because the exponent is 7. • So, 6.03 x 107 = 60,300,000 • Try one with a negative exponent. • Ex.2 Change 5.3 x 10-4 to standard notation. • The exponent tells us to move the decimal four places to the left. • So, 5.3 x 10-4 = 0.00053

  5. CALCULATING WITH SCIENTIFIC NOTATION • Rule for Multiplication - When you multiply numbers with scientific notation, multiply the coefficients together and add the exponents.  The base will remain 10. • Rule for Division – When dividing with scientific notation, divide coefficients and subtract the exponents. The base will remain 10. • Rule for Addition and Subtraction - when adding or subtracting in scientific notation, you must express the numbers as the same power of 10.  This will often involve changing the decimal place of the coefficient.
