MATH MATH Operations To display the MATH MATH menu, press I. When you select a menu item, the name is copied to the cursor location. Functions that are valid for lists return a list calculated on an element-by-element basis. MATH MATH Menu INT÷ MATH NUM PRB 1: INT÷ Displays quotient and remainder. 2: 8DEC Displays answer in decimal form. 3: 3 Cube. 4: 3‡ Cube root. 5: x‡ nth root. 6: NDERIV( Numerical derivative. On the Home screen or from a program, INT÷ (integer divide, MATH MATH, item 1) returns the quotient (or quotient and remainder) resulting from the division of two integers. Each argument can be a list. integerAINT÷integerB When INT÷ is executed on the Home screen, it displays the symbols Q= for the quotient and R= for the remainder. Note: If INT÷ is embedded in an expression, Q= and R= may not be displayed. When used with lists, INT÷ returns a list of quotients only. If the result of INT÷ is used in subsequent calculations, the remainder is dropped, and only the quotient is used. The quotient from INT÷ is returned to ANS. Math, Angle, and Test Operations 2-7
