PPT-Chapter 2 Data and Expressions

With this chapter we begin a detailed discussion of the concepts and techniques of computer programming We start by looking at issues related to the representation manipulation and inputoutput of datafundamental to all computing. Expressions and . Assignment Statements. 1-. 2. Chapter 7 Topics. Introduction. Arithmetic Expressions. Overloaded Operators. Type Conversions. Relational and Boolean Expressions. Short-Circuit Evaluation. Re-expressing data –. Get it straight!. AP Statistics. Straightening data. We cannot use a linear model unless the relationship between the two variables is linear. Often re-expression can save the day, straightening bent relationships so that we can fit and use a simple linear model.. Quick Quiz-Write examples:. 1) An Expression that refers to the King of S.A. in 1912?. 2) An expression that could have variable reference.. 3) An expression with constant reference.. 4) Difference expressions having one referent.. GOAL:. I can write and interpret numerical expressions and compare expressions using a visual model. . Agenda:. Multiply by multiples of 10. Estimate Products. Word Problem of the Day!.
