This means you can input fractions, square roots, derivatives, and other expressions just as they are written. In the Math input/output mode , most calculation results also are displayed using natural display. You also can select a Linear input/output mode if you like, for input and display of calculation expressions in a single line.

10 The examples shown in this User's Guide are mainly presented using the Math input/output mode. <Linear input/output mode> will be indicated for examples that use the Linear input/. output mode. For information about switching between the Math input/output mode and Linear input/. output mode, see the explanation of the Input/Output mode setting under Using the Setup Screen (page 1-34). For information about input and display using the Math input/output mode, see Using the Math Input/Output Mode (page 1-14). u !x('). The above indicates you should press ! and then x, which will input a ' symbol. All multiple-key input operations are indicated like this.
