at the time this material was written, TI-86 screens in this Guide appear smaller than the TI-

85 screens. Screens that appear the same on both calculators are shown for the TI-85.

Basic Operation

You should be familiar with the basic operation of your calculator. With calculator in hand, go

through each of the following.

1. CALCULATING You can type in lengthy expressions; just make sure that you use

parentheses when you are not sure of the calculator's order of operations. As a general rule,

numerators and denominators of fractions and powers consisting of more than one term should be

enclosed in parentheses.

Evaluate

4 * 15 +

895

. Evaluate

(

- 5

8 + 1. 456

(Use (–) for the negative symbol and - for the

subtraction sign.)

Evaluate e

0.027 and e

3*0.027

The calculator will assume you mean the first expression

unless you use parentheses around the two values in the

exponent. (It is not necessary to type in the 0 before the

decimal point.)

2. USING THE ANS MEMORY Instead of again typing an expression that was evaluated

immediately prior, use the answer memory by pressing 2nd (–) (ANS) .
