General Information

The TI-15has two powersources-batteryand solar. It operates inwell-litareas using solar cell, and it operates in other light settings on battery.

Examples: See theExamples page for representative problems and keystroke sequences that demonstrate many of theTI-15’sfunctions and capabilities. Before starting each problem set, reset the calculator by pressing- andsimultaneously to help ensure that your displays are the same as those shown in the examples. In Problem SolvingAuto mode, however, displays will vary from those shown, because these problems are random.

Basic Operations

To turn the TI-15on, press-.

If the calculator is on, press - to turn it off.

APD™ (Automatic Power Down™) turns off the TI-15automatically if no key is pressed for about 5 minutes. Press- after APD to power up again; the display, pending operations, settings, and memory are retained.

Display and Scrolling

" ! # $

The TI-15has atwo-linedisplay; each line has room for 11 characters. Entries that do not fit on the first line wrap to the second, and then scroll when the second line is filled.Exception: When computing fractions, theTI-15displays only one line, which scrolls when a problem exceeds the capacity of the line.

Entries can be up to 88 characters. Exceptions: In Stored Operations, the limit is 44 characters. In ‹Man mode, entries do not wrap; entries cannot exceed 11 characters.

When a result exceeds the capacity of the screen, it is displayed in scientific notation. However, if the result is greater than 10^99 or less than 10^L99, you will get an overflow error orunderflow error, respectively.

Scroll with ", !, #, and $.

¦Press " and ! to scroll through entries or to move the underscore within a menu list.

¦Press # and $ to scroll through history or, within a menu, to move to the next level of menu lists.

Integer Division

£

When you divide a positive whole number by a positive whole number with £, the result is displayed in the form Q r R, whereQ is the quotient andR is the remainder.

If you use the result of integer division in a subsequent calculation, the TI-15uses only the quotient; the remainder is dropped.

Fractions ž ¥ • ¢ ¦ ¤ §

Ÿ

Press ž after entering a number to designate the numerator of a fraction.

Press ¥ after entering a number to designate the denominator of a fraction.

Both numerator and denominator must be integers. If you enter a denominator greater than 1000, or if a calculation yields a denominator greater than 1000, the TI-15displays results in decimal format.

You can input either the numerator or the denominator first.

• separates the whole number from the fraction in a mixed number.

¢ displays a menu that lets you specify how fraction results are displayed.

¦U n/d (default) displays results as mixed numbers.

¦n/d displays results as simple (improper) fractions.

¢$ displays a menu that lets you specify the simplification method.

¦Man (default) requires manual simplification of fractions.

¦Auto automatically reduces fraction results to lowest terms.

N/D"n/d indicates that fraction results can be simplified.

¤ enables you to simplify a fraction manually.

§ displays the factor that was used to simplify a fraction in your last manual simplification step. Press § again to restore the fraction to the screen.

¦ converts a mixed number to an improper fraction or an improper fraction to a mixed number.

Ÿ converts a fraction to a decimal, or converts a decimal to a fraction, if possible.

If a problem contains both fractions and decimals, the results are displayed in decimal format. However, if you press ‡ and select n/d, the results of division will be displayed in fraction format, when possible.

Percents

ª y

Press ª after a entering a value to calculate a percent.

Press y to convert a decimal or a fraction to a percent.

Roots and Powers

¨ ¬

¬ lets you obtain the square root of a number. After entering the number, be sure to close the parentheses.

¨ raises a number to the power you specify.

Pi

©

© enters the value of p, which is stored internally to 13 digits (3.141592653590). In some cases, results display with symbolicp, and in other cases as a numeric value.

Memory

z |

After a calculation, press z® to store the displayed result in memory. If memory already contains a value, the new one will replace it. When memory contains a value other than 0, M displays on the screen.

To recall the value from memory for use in a calculation, press | once.

To clear memory, press ||.

Stored Operations

› œ

Op1 andOp2 each can store an operation with a constant value, which you can repeat by pressing only one key, as many times as desired.

1.Press › or œ.

2.Enter the operator first (+, -,Q, P, IntP, or ^) and then the number.

3.Press › or œ.

4.Initialize with a starting value.

5.Each subsequent time you press › or œ, the operation with the constant is applied.

The computation with the stored operation appears on the first line of the display, and the result appears on the second line. If you don’t want the computation line to display, press ‡$"® to hide it. Or, if the expression does not fit on the line, it will not show. When space permits, a counter on the second line shows how many times you have pressed › or œ.

To clear the contents of Op1 orOp2, press ‡$$, selectOp1 orOp2, and press ®. Then press ‡ to return to the last result display.

Rounding Š • ‘ ’ “ ˜ ™ š

You can round results with Š in conjunction with place value keys to specify a given number of places. (The internally stored value is not rounded.) The calculated value is padded with zeros as needed. You must press Š again each time you change the number of places.

Keys Action

Š• Rounds in thousands.

Š‘ Rounds in hundreds.

Š’ Rounds in tens.

Š“ Rounds in ones.

Š˜ Rounds to nearest tenth.

Š™ Rounds to nearest hundredth.

Šš Rounds to nearest thousandth.

Šr Removesfixed-decimalsetting.

These place-valuekeys also work with Π(see below).

Problem Solving

‹ • Ž

The ‹ function lets you practice and test your skills in arithmetic. You can choose either Auto orMan mode.

In ‹ Auto mode (default), theTI-15presents 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 ‹, press ‡$ to access the menu list and press " or ! to select the desired level of difficulty (1, 2, or 3). Then press ®‡, and the TI15 will present problems at the selected level.

Type of Problem. While in ‹, press ‡$$ to access the menu list, and press " or ! to select the desired type of problem (addition, subtraction, multiplication, division, or find the operator). Then press ®‡, and theTI-15will present problems of the selected type.

1.You enter an answer.

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 “No” 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, and you enter another answer to that same problem.

5.If you enter three incorrect answers to a given problem, the TI-15shows the correct answer, clears that problem, and presents a new problem.

Scoreboard. TheTI-15shows a Scoreboard after every fifth problem. Every correct solution you have entered registers a “Yes” in the Scoreboard, and three incorrect answers in a row register one “No.” After 100, the Scoreboard returns to zero.

Problem Solving

(continued)

When you first enter ‹ and when you press ‡, the display shows the Scoreboard for a moment before presenting problems or before showing the menu.

In ‹ Man (manual) mode, you compose your own problems. While in ‹, press ‡ to access the menu list, and press " to selectMan. Then press ®‡, and theTI-15is ready for you to enter your problem and your solution. It accepts onlynon-negativeintegers in this mode. You indicate a missing element with •.

In ‹ Man mode, it is possible to enter a problem that has one solution, multiple solutions, or no solution. TheTI-15tells 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 so you can enter a new problem.

¦Problems with two missing elements have multiple solutions. For example, ?+?=5 has 6 solutions; ?x?=24 has 8 solutions. (In this type of problem, the question marks replace the operands; they 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; the problem remains so you can enter other

solution sets, until you clear the problem manually by pressing .

¦When the answer to a problem is not a positive integer (such as 9P2), the TI-15indicates that it has zero solutions. But if you enter answers, it will tell whether they are greater than or less than the correct answer.

Inequalities. Instead of entering an equation, you can test an inequality using Ž. You get only one try, because the inequality statement is either true or false. With inequalities you can enter decimals. Press Ž once for <, and press Ž twice for >.

To exit Problem Solving, press ‹ again.

Place ValueŒ • ‘ ’ “ ˜ ™ š

While in ‹, Man mode, you can determine the place value of a digit; determine how many ones, tens, hundreds, thousands, tenths, hundredths and thousandths a number contains; or determine which digit of a given number is in a specified place.

¦ Determine Place Value:

LAfter entering a number, you can determine the whole

number place or the decimal place of a given digit by pressing Πand then pressing the digit in question.

LIf you have a number with a repeated digit, when you press this digit the TI-15analyzes itsright-mostoccurrence. To find the place value of those to the left, press the given digit again before the answer appears. Each time you press the given digit in succession, the display shifts to the next occurrence of this digit to the left and shows the place value for this occurrence.

While in ‹, Man mode, you can access a Place Value menu by pressing ‡$.

¦Find out how many ones, tens, hundreds, thousands,

tenths, hundredths, or thousandths a number contains (default): If necessary, press ‡"®$, select the 11- setting, and press ®‡. Enter the number to be analyzed, press Œ, and then press “, ’, ‘, •, ˜, ™, or š.

¦Find out what digit of a number is in a specified place: Press ‡"®$, select the -1- setting, and press ®‡. Enter the number to be analyzed, press Œ, and then press “, ’, ‘, •, ˜, ™, or š.

The answer appears briefly and then clears so you can press another digit or place value key. Once the Πfunction is active, it is not necessary to press this key before each digit or place you wish to examine for a given number. You need to press before entering a new number to analyze and then activate Πagain.

To exit the Πfeature, press .
