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.
