Review of Introductory Mathematics SCIENTIFIC NOTATIONSCIENTIFIC NOTATIONThis chapter covers the addition, subtraction, multiplication, and division ofnumbers in scientific notation.EO 1.13 Given the data, CONVERT integers into scientific notation andscientific notation into integers.EO 1.14 APPLY one of the arithmetic operations of addition,subtraction, multiplication, and division to numbers usingscientific notation.CalculatorUsageScientific Notation keyIf pressed after a number is entered on the display, the EE key will convert thenumber into scientific notation. If a number is to be entered in scientific notationinto the calculator, pressing the EE key tells the calculator the next enterednumbers are the exponential values.Scientists, engineers, operators, and technicians use scientific notation when working with verylarge and very small numbers. The speed of light is 29,900,000,000 centimeters per second; themass of an electron is 0.000549 atomic mass units. It is easier to express these numbers in ashorter way called scientific notation, thus avoiding the writing of many zeros and transpositionerrors.29,900,000,000 = 2.99 x 10^{10}0.000549 = 5.49 x 10^{-4}WritingNumbersinScientificNotationTo transform numbers from decimal form to scientific notation, it must be remembered that thelaws of exponents form the basis for calculations using powers.Rev. 0 Page 67 MA-01
