23456 E-2. Why do we need scientific notation? One example is for calculators. If you multiply 1,234,567 by 1,234,567, would you have enough spaces to list the entire answer? Another example is if everyone in the United States owned an equal portion of the Washington monument, how much would that be? ) Other Examples of Scientific Notation = 1 × 102 1000. 00000100 = 1 × 10-6 1,000,000. How to Convert from Standard Notation to Scientific Notation Convert the number 3789 to scientific notation. The decimal point in this number is after the 9.

Sometimes we feel that to be technical we need to limit ourselves to big words, data, and graphs. Even the most technical reader, however, appreciates the value of understanding the message clearly through an image rather than by reading more words. As an example, consider a gear pump. Most people, when first learning about these devices, assume the direction of rotation incorrectly. It would take a fair amount of writing to explain the proper rotation in a way that would ensure that the reader understands and remembers.

So why would one design a system like this? Precision. What would be sacrificed? If the steps were 10 psi, one could not expect the system to give 95 psi, or 1257 psi: They would have to be multiples of 10. The accuracy would not be as great, but the precision would be there. At least one molding machine manufacturer has produced machines where the steps consisted 14 ® CHARTS AND GRAPHS KIRK M. CANTOR ® INTRODUCTION more effective way. Now, consider the following graph of the race data above: This section covers creating and using charts and graphs, tools that we use to present data.
