HP 50g manual

Notice that, if your CAS is set to EXACT (see Appendix C in user’s guide) and you enter your expression using integer numbers for integer values, the result is a symbolic quantity, e.g.,

In this case, when the expression is entered directly into the stack, as soon as you press `, the calculator will attempt to calculate a value for the expression. If the expression is preceded by a tickmark, however, the calculator will reproduce the expression as entered. For example:

³5*„Ü1+1/7.5™/

„ÜR3-2Q3`

The result will be shown as follows:

To evaluate the expression we can use the EVAL function, as follows:
