Relational operators are often used in programs to control program flow and in graphing

to control the graph of a function over specific values.

Relational operators are evaluated after mathematical functions according to EOS rules

(Chapter 1).

• The expression 2+2=2+3 returns 0. The TI-84 Plus performs the addition first

because of EOS rules, and then it compares 4 to 5.

• The expression 2+(2=2)+3 returns 6. The TI-84 Plus performs the relational test first

because it is in parentheses, and then it adds 2, 1, and 3.
