Two-Number Functions

When a function requires two numbers, other than for addition, subtraction, multiplication, division, and the power function, (yx ), you may key in the numbers as follows: number1 Æ

number 2 followed by the operation. Pressing Æevaluates the current expression and displays the INPUT annunciator.

In-line Functions

For calculations involving \¨, \Ä, \Ç, ]9,

]<,]I, and ]oI, which require two numbers, you may also key in the first number followed by the function keys, and then key in the second number followed by 4to return results. Throughout the manual, when examples are entered in this

manner without using Æ, they are referred to as in-linefunctions. For example, the

following keystrokes calculate the percent change between 17 and 29 using the \¨ keys as an in-line function:
