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.
