TWO-NUMBER FUNCTIONS

The calculator performs two-number math functions using two values entered sequentially into the display. If you are **keying in** both numbers, remember that they must be separated by ENTER or any other function-like g INT or 1/x-that terminates digit entry.

For a two-number function, the first value entered is considered the y-value because it is placed into the Y-register for memory storage. The second value entered is considered the x-value because it remains in the display, which is the X-register.

The arithmetic operators, +, -, *, and ÷, are the four basic two-number functions. Others are given in following entries of the table of contents.
