Texas Instruments Titanium TI-89 Quick start guide

Discovering Advanced Algebra Calculator Notes for the Texas Instruments TI-89, TI-92 Plus, and Voyage 200 CHAPTER 0 1

Note 0A • Order of Operations

To evaluate expressions, the calculator uses the standard order of operations,

PEMDAS (parentheses, exponents, multiplication and division, addition and

subtraction). For example, when you enter the expression 1124*3

a. The calculator reads no parentheses or exponents.

b. The calculator does multiplication and division from left to right: it

evaluates 124 as 3 to get 1 3*3, and it evaluates 3 *3 as 9 to

get 1 9.

c. The calculator does addition and subtraction from left to right: it

evaluates 1 9 as 10.

Negation is on the same level as multiplication, so powers are calculated

before negation. For example, 4^2 evaluates as 16.Tosquare 4, you use

parentheses: (4)^2.

Although there are keys for the brackets, [ ],and braces, { },you use for

grouping when working on paper, the calculator uses them for other things.

To group on the calculator, you use only the parentheses keys. So, to evaluate

the expression





•4



,you enter (53)(2*4)(





(81)4)(2(72))2.

Study these examples and verify the results on your calculator.

Note 0B • Fractions

depends on the Exact/Approx setting on the Mode screen. Press , arrow

twice to confirm and return to the Home screen. Your choice is shown in
