uMath Input Mode Calculation Result Display

Fractions, matrices, and lists produced by Math input mode calculations are displayed in 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 “1-8 Using the Setup Screen”.

#Matrices are displayed in natural format, up to 6 ⋅ 6. A matrix that has more than six rows

or columns will be displayed on a MatAns screen, which is the same screen used in the Linear input mode.

#Lists are displayed in natural format for up to 20 elements. A list that has more than

20 elements will be displayed on a ListAns screen, which is the same screen used in the Linear input mode.

#Arrows appear at the left, right, top, or bottom edge of the display to let you know when there is 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(DEL)1(DEL • L) while a calculation result is selected will delete both the result and the calculation that produced it.

#The multiplication sign cannot be omitted immediately before an improper fraction or mixed fraction. Be sure to always input a multiplication sign in this case.

Example: 2 ⋅ 52 c*$ccf

#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 operations separate.

Example: (32)–1

(dx)!)(x–1)
