Ulysses Harrison, Dunbar Vocational High School  
A lesson designed to teach students to group the set, R, of real numbers into two different sets: R > 0, R < 0; use parentheses to change the order in which exponentiation, multiplication, division, addition and subtraction are performed by using the TI34 calculator; and work problems throughout the set of real numbers using the TI34 calculator without preference for positive numbers. From the Practical and Applied Math section of a collection of almost 200 single concept lessons by the Science and Mathematics Initiative for Learning Enhancement.
