SCIENTIFIC NOTATION * Scientific notation is a way of writing very large and very small numbers in a compact form. * A number written in scientific notation is written in the form: a x 10b WRITING A NUMBER IN SCIENTIFIC NOTATION * Shift the decimal point so that there is one digit before the decimal point. * Multiply by a power of 10‚ equal to the number of places the decimal point has been moved. * The power of 10 is positive if the decimal point is moved to the left and negative

Topic: Scientific Notation II. Objectives: To be able to fully understand the lesson‚ the student must learn: a. the definition of scientific notation b. the purpose of scientific notation c. how to make a number in scientific notation and vice versa III. Motivation: Recalling the names of numbers by its number of zeroes IV. Lesson Proper: * A number is in scientific notation when it is written as N x 10n‚ where 1<N<10 and n is an integer. * Scientific notation

POSTFIX NOTATION Postfix also known as Reverse Polish Notation (or RPN)‚ is a notational system where the operation/function follows the arguments. For example‚ "1 2 add" would be postfix notation for adding the numbers 1 and 2. Most programming languages use either prefix notation ("add(1‚ 2)" or "(add 1 2)") or infix notation ("1 add 2" or "1 + 2"). Prefix and infix are more familiar to most people‚ as they are the standard notations used for arithmetic and algebra. Why then should we use postfix

Using Scientific Notation Geo Labs Gioppo 2012 © Introduction We use scientific notation to make it more convenient to write out very large‚ or very small numbers. It also helps us avoid making mistakes when writing the numbers‚ like having one too many (or too less) zeros. Think of it as a short hand system –that happens to be based on powers of ten. You’ve done this before in school‚ remember 101 = 10‚ 102 = 100 103 = 1000‚ etc.? This is the same idea‚ we just write it a little

directions of search for efficient algorithms. Big O notation In computer science‚ big O notation is used to classify algorithms by how they respond (e.g.‚ in their processing time or working space requirements) to changes in input size. Big O notation characterizes functions according to their growth rates: different functions with the same growth rate may be represented using the same O notation. A description of a function in terms of big O notation usually only provides an upper bound on the growth

The Scientific Method - The Scientific Method is the standardized procedure that scientists are supposed to follow when conducting experiments‚ in order to try to construct a reliable‚ consistent‚ and non-arbitrary representation of our surroundings. To follow the Scientific Method is to stick very tightly to a order of experimentation. First‚ the scientist must observe the phenomenon of interest. Next‚ the scientist must propose a hypothesis‚ or idea in which the experiments will be based around

Scientific notation is used as a shorthand way of writing very large and very small numbers. 2. The decimal point is placed after the first significant figure‚ and then this decimal is multiplied by the appropriate power of 10. 3. The power of 10 is found as follows
