Operations and Operators Copyright 2014 Scott Storla

Absolute Value Copyright 2014 Scott Storla

Integers have two attributes, a size (how much, how many) and a sign (positive or negative). For instance $2 has a size of 2 and it’s positive, we have $2. – $2 also has a size of 2 and it’s negative, we owe $2. Copyright 2014 Scott Storla

Procedure – Order of Operations Starting with the innermost type of grouping and working out 1.Perform all operations beyond the basic four. 2.Multiply and divide, left to right. 3.Add and subtract, left to right. Absolute value is both an operator and an implicit grouping symbol. Copyright 2014 Scott Storla
