SCIENTIFIC NOTATION Review of Introductory MathematicsStep 3: Rewrite the number in integer form.Example:Convert 4.4 x 103 to integer form.Solution:AdditionIn order to add two or more numbers using scientific notation, the following three steps must beused.Step 1: Change all addends to have the same power of ten by moving the decimalpoint (that is, change all lower powers of ten to the highest power).Step 2: Add the decimal numbers of the addends and keep the common power often.Step 3: If necessary, rewrite the decimal with a single number to the left of thedecimal point.For example, for 3.5 x 103 + 5 x 102 you are asked to add 3.5 thousands to 5 hundreds.Converting 3.5 thousands to 35 hundreds ( 3.5 x 103 = 35 x 102) we obtain 35 hundreds + 5hundreds = 40 hundreds or 3.5 x 103= 35 x 102+ 5 x 102= 4 x 103. The student should dothe same problem by converting the 5 x 102 to thousands and then adding.Example:Add (9.24 x 104) + (8.3 x 103)Solution:Step 1: 9.24 x 104 = 9.24 x 1048.3 x 103= 0.83 x 104MA-01 Page 70 Rev. 0
