Decimal places How do I determine how many decimal places will be in my answer for a math problem of subtraction and addition? I am confused when it says : I have a number with two decimal places and the result come's to something like this "19" example: ( 5.489-5.01) x 6.78 x 5.903 equals 19.1707 . If the decimal places are two. why is it only 19 ? Shouldn't it be 19.17 ?

Divide inches x12 gives feet and a decimal .
multiply the foot answer by 12 subtract the answer from the original number this is the remaining inches now you have feet and inches answer. Don't they teach math any more?

Use the >Frac and >Dec commands in the MATH menu. Press the MATH button to bring up the menu.

How do I program tax rate into my calculator?
Non-printing models (also applies to HR-8TE printing calculator):

1. Press [AC]
2. Hold [SET/%] key for about 2 seconds
3. Press [TAX+]
4. Input the tax rate
5. Press [SET/%]


Printing models (except HR-8TE):

1. Have calculator in "print" mode
2. Press [CA]
3. Hold [SET/%] key for about 3 seconds
4. Input the tax rate
5. Press [TAX+]
6. Press [SET/%]

Enter only the numerals, not the letters.
^Top What features do our calculators have?
The attached chart shows comparisons of the different calculator models. This includes graphing, scientific and printing calculators. download the chart here
^Top What is the [F CUT 5/4] switch or [DEC] F, 0, 2 button for?
The HR-8TE/HR-8TM have a [DEC] key with F, 0, 2, and 5/4 over it, while many other calculators models have a switch labeled [F CUT 5/4].
The button or switch can control rounding off to a certain number of decimal places. F is floating point (no F indicator on screen), 0 rounds off to 0 places after decimal point, and 2 rounds off to 2 places after decimal point.
The 5/4 applies to either the 0 or 2 modes, and describes the type of rounding off that is performed. The calculator will round down if the digit after the one you are rounding to is 4 or lower, and round up if the digit is 5 or higher.
^Top What is the [5,4,3,2,1,0 ADD (2)] switch used for?
This switch is used to determine how many decimal places your answer is displayed in.
ADD (2) is often used for monetary calculations, so that it is not necessary to enter the decimal point. It is automatically placed two decimal places from the end for cents. For example, entering 123 will display as 1.23.
^Top Why do I get 111.1111... when I calculate 100+10%?
This is a markup on price procedure. The formula is as follows:
Markup%=(Markup Price-Cost)/(Markup Price)
^Top Why do I get the wrong answer when doing a percent calculation?
Make sure that you are following the correct procedure.
Adding 10%: 200 [×] 10 [%] [+]
Subtract 10%: 200 [×] 10 [%] [-]
^Top What tests are calculators permitted for?
AP Calculus requires a graphing calculator.
Any graphing or scientific calculator is permitted on the following as long as it does not have a QWERTY keyboard, electronic writing pad or a pen-input/stylus-driven interface:
PSAT/NMSQT, SAT I
SAT II Math, IC & IIC
AP Statistics (graphing expected)
AP Chemistry
AP Physics

PRINT KEY: To save paper you can only print what is displayed, even in non-print mode. Pressing after the entry of a number will print the entry with the symbol “#” even in non-print mode. Pressing will insert a separator into a number entry such as a code, date, etc. Separators are displayed as a period and dashes but printed as periods. MEMORY + KEY / PRINT ON / OFF KEY: Pressing selects print mode or non-print mode. Cause the calculator to operate in a display / print or display only mode, depending upon the calculator’s present state. “P” on the display: Print mode. “NP” on the display: Non-print mode. MEMORY – KEY / DECIMAL SELECTION KEY: Pressing sets the number of decimal places in the result. “F” on the display: The answer is displayed in the floating decimal system. “3, 2, 1, 0” on the display: Presets the number of decimal places in the answer. “A” on the display (Add mode): The decimal point in addition and subtraction entries is automatically positioned to the 2nd digit from the lowest digit of entry number. Use of the add mode permits addition and subtraction of numbers without entry of the decimal point. Use of , and will automatically override the add mode and decimally correct answers will be printed.

Access http://www.google.com
and enter '72.63-1.50' and press ENTER.

Google Math will give you the answer. :-)

Check the Decimal / Add Selector. It shoul be set to "A" (Add mode), to permit addition and subtraction of numbers without entry of the decimal point.

Hello desireejane,


One method is to do the following

1. Convert the octal, hexadecimal or binary to decimal.
2. Add or Subtract the decimal normally
3. Convert the result back to octal, hexadecimal or binary.

• Convert the octal to decimal:

public static long octalToDecimal(String octal) throws NumberFormatException {
// Initialize result to 0
long res = 0;

// Do not continue on an empty string
if (octal.isEmpty()) {
throw new NumberFormatException("Empty string is not an octal number");
}

// Consider each digit in the string
for (int i = 0; i < octal.length(); i++) {
// Get the nth char from the right (first = 0)
char n = octal.charAt(octal.length() - (i+1));

int f = (int) n - 48;
// Check if it's a valid bit
if (f < 0 || f > 7) {
// And if not, die horribly
throw new NumberFormatException("Not an octal number");
} else {
// Only add the value if it's a 1
res += f*Math.round(Math.pow(2.0, (3*i)));
}
}

return res;
}

When performing the calculations, put the fractions in parentheses. Then once you get your answer, press 2nd and Math (above the times button). Then press F5, MORE, and F1. It will have Ans Frac>. Then hit Enter and it'll change it to a fraction.

If i type 10+10 it comes up with 10+10=20 and my setting is on Math G . So mabey try that ?
