Question about Texas Instruments TI-83 Plus Calculator

For example when i do .003/365 my calculator says 8.23E-6 but in my online class that is not the correct answer. And it is not in engineering mode.

The correct answer would be 8.22E-6 . Even if you're not in scientific or engineering mode, the calculator will automatically switch to scientific mode if the absolute value of the number is less than 0.001 (or won't fit in ten digits).

SOURCE: negative answer when squaring a neg number

You must put all negative numbers in Parenthesis otherwise your calculator is not squaring the negative .

SOURCE: how do you use exponents in this calculator?

There is a ^ button on the right side of the calculator so 2^2=4 and 2^3=8..

SOURCE: The calculator won't convert fractions into decimals

Are you using a ti-89? If so, check your mode settings and change Exact to Approximate.

SOURCE: I just bought a texas instruments TI-30X IIS

if you want to use your calc for this you would have to put it in as the operations to change the mixed to improper fraction i.e. input exactly as "((8*3)+6)*((3*7)+1)=" remember? take denominator times whole number plus numerator and put over denominator to convert from mixed to improper... hope this helps

SOURCE: need to program to fifth decimal place

Your BA II PLUS stores numeric values internally to an accuracy of 13 digits. However, the numbers it displays depends on the number of decimal places to which you have it set (choice of 0–9 or floating decimal). To set the number of decimal places displayed to three: hit [2ND][FORMAT][5][ENTER]This setting also continues indefinitely (even though the calculator is turned off and on) until it is changed.

Meaning what, exactly?

If you want a decimal representation of an exact number, press the SD key to switch from exact to approximate (decimal). If you want to expand a decimal number in powers of 10, separate all the digits, multiply every digit by a power of 10 with exponent equal to its position as counted from the decimal mark -1. To the left of the decimal mark, the exponent is positive. To the right of the decimal mark, the exponent is negative. Sum everything

Example

345.678 =3*10^(3-1)+4*10^(2-1)+5*10^(1-1)+6*10(-1)+7*10^(-2)+8*10^(-3)

The calculator has three display formats for results: Normal, Scientific, and Engineering. It is possible that your calculator is configured to display results in Scientific Format.

Press the MODE button. On the first line, highlight Normal. After that you can use the Down Arrow to move cursor to the second line and highlight FLOAT.

There is a misconception hiding here in your statement. A decimal result on a calculator is often no more than an approximation: Try expressing 1/3 as a finite decimal representation. So, the only exact results that you may get are those displayed as fractions and those with radicals.

Now let us address your question. The calculator has a limited display capability. Any decimal result that is too small or too large to fit in the display window will automatically be displayed in scientific notation (the one with exponents).

If you want exact results, you should set the Input/output to MathIO. Even then, if the expression requires more display space than is available, it will be displayed as a decimal number.

In the default NORM1 display mode, values whose magnitude are less than 0.01 are automatically displayed in scientific notation.

Press SHIFT MODE 8 2 to select the NORM2 display mode. In this mode, the calculator does not switch to scientific notation until the magnitude drops below 0.000000001 .

This is all described in the "Calculation Modes and Calculator Setup" section of the manual, beginning on page E-7.

For square roots, use the square root key just to the left of the divide key. For example, 4 square-root = will give you 2.

The calculator doesn't have any way to store equations, scientific or otherwise. If you mean scientific notation, use the EE key just above the 7 key to enter exponents. For example, to enter 1.23x10^6, press 1 . 2 3 EE 6. For negative exponents, make sure to use the +- key to the right of the decimal point instead of the - key.

To enter decimal exponents, use the x10^x key below the 3, followed by the exponent. For example, to enter one million, press 1 x x10^x 6 and see 1000000 (actually, the leading one is optional: if you press x10^x without a value, the calculator will supply a 1).

To raise a value to a number, use the x^ key above the sin, followed by the exponent. For example, to calculate 2^3, press 2 x^ 3 = and see 8.

Scientific notation is a number format that has the following structure (d stands for digit)

one digit decimal mark several other digits [times] 10 raised to power of exponent

d [decimal mark] dddddd...[x] 10^ (-) dd

Here are two examples the last two results. The number of digits after the decimal mark is select by the user depending on the number of significant digits in the data. The exponent can be positive or negative.

In you case, to enter x10^ you press the [EE] key (no 10 is entered) the sign of the exponent and the value of exponent.

The calculator has several decimal display formats: FIX, SCI, NORM and ENG.

Here are examples of calculations with different formats and how to set them.

It may be a good idea for a user to get accustomed to the scientific display format, because it is the one most calculators adopt when the result to be displayed is too large or too small--when there are not enough places on the screen to display the result.

To help you with the power of 10 notation

1 billion =1000 000 000 =1 E 09 (9 zeros after 1 >> exponent 9)

1 million=1 000 000 = 1 E 06 (6 zeros after 1 >> exponent 6

1 thousand= 1000 =1 E03 (3 zeros after 1 >> exponent 3)

One= 1 = 1 E0

One tenth = 1/10 =0.1: the 1 is ONE position after the decimal mark>> exponent -01

One hundredth =1/100 =0.01 the 1 occupies the 2ND position to the right of the decimal point, exponent -02

etc.

1/1000 =0.001 = 1E-03

1/10000=0.0001=1E-04 (1 in 4th position to the right of decimal mark)

1/1000000=0.000001 = 1E-06 (1 in 6th position to the right of decimal mark)

1E-09 =0.000000001 : the 1 is in the 9th position to the right of decimal mark.
