1-20k Math Input/Output Mode Calculation Result DisplayFractions, matrices, and lists produced by Math input/output mode calculations are displayedin natural format, just as they appear in your textbook.Sample Calculation Result Displays• Fractions are displayed either as improper fractions or mixed fractions, depending on the“Frac Result” setting on the Setup screen. For details, see “Using the Setup Screen” (page1-32).• Matrices are displayed in natural format, up to 6 × 6. A matrix that has more than six rows orcolumns will be displayed on a MatAns screen, which is the same screen used in the Linearinput/output mode.• Lists are displayed in natural format for up to 20 elements. A list that has more than 20elements will be displayed on a ListAns screen, which is the same screen used in the Linearinput/output mode.• Arrows appear at the left, right, top, or bottom edge of the display to let you know when thereis more data off the screen in the corresponding direction.You can use the cursor keys to scroll the screen and view the data you want.• Pressing 2(DELETE)1(DEL-LINE) while a calculation result is selected will delete boththe result and the calculation that produced it.• The multiplication sign cannot be omitted immediately before an improper fraction or mixedfraction. Be sure to always input a multiplication sign in this case.Example: 2× 25 c*cvf• A M, x, or !)(x–1) key operation cannot be followed immediately by another M,x, or !)(x–1 ) key operation. In this case, use parentheses to keep the key operationsseparate.Example: (3 2 ) –1 (dx)!)(x–1 )
