General Information

The TI-10 has two power sources — battery and solar. It

operates in well-lit areas using the solar cell, and it operates

in other light settings using the battery.

Examples

: See the “Examples” page for problems with

keystroke sequences that demonstrate many of TI-10

functions and capabilities. Before starting each problem set,

reset and clear the TI-10 by pressing

Division

When you divide a positive whole number by a positive

whole number using

, the result is displayed in the form Q

r R, where Q is the quotient and R is the remainder. For

example, if you are in the QR setting: 12

2 r 2.

If you use the result of QR division in a subsequent

calculation, the TI-10 uses only the quotient. The remainder

is dropped.

For decimal results, select the decimal division setting by

pressing



[

Problem Solving lets you practice and test your skills.

To enter Problem Solving, press



You can choose either AUTO (automatic) or MAN (manual)

mode.

AUTO Mode

‹

(Problem Solving) AUTO mode (the default), the TI-10

presents problems with one element missing, for example:

5+2=? or 5+?=7 or 5?2=7. You can select the type of

problem and choose from three levels of difficulty. The

default is addition at Level 1.

Level of Difficulty

. While in

‹

AUTO mode, press

‡$

to access the menu. Press

to select the level of

difficulty (1, 2, or 3). Press

‡

, and the TI-10 will

present problems at the selected level. Or, while in

‹

mode, press

to advance to the next level. After Level

3, pressing

again returns you to Level 1.

Type of Problem

. While in

‹

AUTO mode, press

‡$$

to access the menu. Press

to select

the type of problem — addition (+), subtraction (

multiplication (

), division (

), or find the operator (?). Press

‡

, and the TI-10 will present problems of the

selected type.

Procedure.

When a problem is presented:

1. Enter an answer and press

2. If your answer is correct, the display shows

YES, clears the

screen, and presents another problem.

3. If your answer is not correct, the display shows

and indicates

whether the correct solution is less than

or greater than

the

answer that you entered.

4. The incorrect answer is cleared from the display so you can enter

another answer to that same problem.

5. If you enter three incorrect answers to a given problem, the TI-10

shows the correct answer, clears that problem, and presents a

new problem.

Scoreboard

. The TI-10 shows a Scoreboard after every fifth

problem. Every correct solution you entered registers one

YES in the Scoreboard, and three incorrect answers in a row

in the Scoreboard. After 100, the

Scoreboard returns to zero.

Press

‡

to display the Scoreboard at any time. The

Scoreboard is then replaced by the AUTO / MAN menu after

a few seconds. Press

‡

again to return to the problem.

MAN Mode

Using

‹

(Problem Solving) MAN (manual) mode, you can

compose your own problems.

1. Press

‡

to access the menu.

2. Press

to underline MAN.

3.Press

‡

The TI-10 is ready for you to enter your problem and your

solution. The TI-10 accepts only non-negative integers in

this mode. To indicate a missing element, press



‹

(Problem Solving), press

]

to change between

AUTO and MAN

mode. Auto shows in the top line of the

display when Problem Solving AUTO is selected.

‹

MAN mode, it is possible to enter a problem that has

one solution, multiple solutions, or no solution. The TI-10

tells you how many solutions the problem has.

Problems with one missing element generally have only one

solution. You get three tries. After three incorrect answers, the

calculator displays the correct answer and then clears the display

so you can enter a new problem.

Problems with two missing elements may have multiple solutions.

For example: ?+?=5 has 6 solutions; ?x?=24 has 8 solutions. For

multiple-solution problems, the question mark replaces the

operands. Question marks may not appear in the place of the

operator or the answer. These problems are not cleared after a

correct solution or after three incorrect answers. Instead, the

problem remains so that you can enter other solution sets. To

clear the problem at any time, press

”

When the answer to a problem is not a positive integer (such as

2), the TI-10 indicates that the problem has zero solutions.

-3-

However, if you enter an answer, it will tell you whether your

answer is less than

or greater than

the correct answer.

Inequalities

. Instead of entering an equation, you can test an

inequality using

[

. You get only one try because

the inequality statement is either true or false. With

inequalities you can enter decimals.
