This number representation uses 4 bits to store each digit from 0 to 9 For example 1999 10 0001 1001 1001 1001 in BCD BCD wastes storage space since 4 bits are used to store 10 combinations rather than the maximum possible 16 BCD is often used in b Consider the coordinate system illustrated in Figure 1 Instead of using the typical axis labels and we use and or 1 The corresponding unit basis vectors are then and or 1 The basis vectors and have the following properties 1 1 0 2 Figu Each digit is multiplied by an appropriate power of 10 depending on its position in the number For example 843 8 x 10 4 x 10 3 x 10 8 x 100 4 x 10 3 x 1 800 40 3 For whole numbers the rightmost digit position is the ones position 10 1 The Data Representation. Representing Real numbers. Need to represent numbers such as . 0.543. or . -17.45. The decimal system uses the “decimal point”. Remember the definition of a number system, but extended to negative exponents. Objectives. Express numbers in scientific notation.. Convert from standard form to scientific notation.. Convert from scientific notation to standard form.. Add, Subtract, Multiply, and Divide with scientific notation..                                  . Starter. 1. . Count the number of stars and give your best estimate.. 2. Why is it difficult to work with LARGE numbers?. Scientific Notation . Scientific Notation Intro. Scientific Notation. Consists of two parts. 1. mantissa. The full size number that comes before x 10. 2. characteristic. The exponent that comes after x 10 and is superscript. ECF Arbiter Seminar - Material by CAA. Notation. Algebraic notation should be used as given in Appendix C of the Laws of Chess.. Some older British players still use descriptive. Therefore knowing descriptive is useful but will not be taught in this course (though these notes will show the moves in descriptive for info).. Concurrency Topics. 1. Sequential programming notation. 2. Expressing concurrency with . co. and . process. . 3. States and hardware. 4. Atomic actions. 5. Inter-leavings and histories. 6. The finite progress assumption. Multiplying Numbers in Scientific Notation. Multiply the decimal numbers together.. Add the exponents to get the power of 10. . General formula. : . . (N X 10. x. ) (M X 10. y. ) = (N) (M) X 10. Lesson 2-5. Dividing a Decimal by a Decimal. We NEVER want a decimal in the divisor.. If you have a decimal in the divisor, you need to bump it over until it is all the way over to the right of the number.. Please get out paper for today’s lesson. --------------------------------------------------------. Name. Date. Period. Perform operations with . numbers expressed in scientific notation, including problems where both decimal and scientific notation are . Do Now: Fill in chart.. Homework#1-9:. Finish Worksheet. What is scientific notation?. Scientific notation is a way of representing really small or really large numbers. Who uses scientific notation?. 210,000,000,000,000,000,000,000 miles. (22 zeros). This number is written in decimal notation. When numbers get this large, it is easier to write them in scientific notation.. Scientific Notation. A number is expressed in scientific notation when it is in the form.
