Mvalue EOS™ rules (Chapter 1) determine when negation is evaluated. For example, L42 returns a negative number, because squaring is evaluated before negation. Use parentheses to square a negated number, as in (L4)2. Note: On the TI-84 Plus, the negation symbol (M) is shorter and higher than the subtraction sign (N), which is displayed when you press ¹. Pi p (Pi, y B) is stored as a constant in the TI-84 Plus. In calculations, the TI-84 Plus uses 3.1415926535898 for p. MATH Operations MATH Menu To display the MATH menu, press .
