Question about Calculated Industries Construction Master IV 4045 Calculator

When I press in a number, say, 2 feet, 3 1/2 inches, the calculator automatically rounds up to 2 feet, 4 inches. Is there a function key that can stop this?

You can combine all the feet together 10+5+11=26 feet

Combine all the inches together -3-4-11=-18 inches=-2 ft + 6 inches

26 ft -2ft +6 inches =24 ft +6 in=24.5 ft

You can also multiply each inch -value by 1/12

10-3/12+5-4/12+11-11/12=10+5+11 -(3+4+11)/12=26-18/12, continue

Combine all the inches together -3-4-11=-18 inches=-2 ft + 6 inches

26 ft -2ft +6 inches =24 ft +6 in=24.5 ft

You can also multiply each inch -value by 1/12

10-3/12+5-4/12+11-11/12=10+5+11 -(3+4+11)/12=26-18/12, continue

4 inches is 1/3 feet, so multiply 4 feet by 2 feet by 1/3 feet to get 2 2/3 cubic feet.

Are you entering any number before pressing the minus, add, multiply, or divide key? Those operations require two numbers; if you don't supply the first one then the calculator will supply the previous answer, which was zero.

For example, to add 2 and 3, press 2 + 3 = and you'll see 5. Now to add 4 to that, press + and the calculator will automatically supply the 5. Press 4 = and you'll see 9.

Minus and change-sign are two completely different things. Minus is used to subtract one number from another. When you press minus when the input line is empty, your telling the calculator to subtract. The only way it can subtract the number you're about to put in is to subtract it from something else, and that something else is the previous answer, hence the "Ans."

If you want to input a negative number, use the change-sign key. If you want to subtract one number from another number, use the minus key.

Try pressing the plus key when the input line is empty. You'll get Ans+ in this case as well, The same with multiply and divide, among others, and for the same reason.

MOD simply calculates the remainder that is left over after dividing by the MOD parameter.

For example, 10MOD7 = 3 since you can only divide 7 into 10 once, leaving a remainder of 3.

For larger numbers, eg 389487MOD31 you start by dividing 389487 by 31, which gives 12564.09677 (on the display), however you only want the fractional part so subtract 12564 to give 0.0967741935 . This includes the lower value digits that were previously hidden. Then multiply this result by 31 which gives 2.999999999 on the display. Since the result of a MOD calculation has to be a whole number, the answer needs to be rounded to 3. If the answer doesn't easily round to a whole number, it is likely that you have gone beyond the calculators working capacity.

An alternative method is to take the integer part of the first result (12564) and multiply it by 31 to get 389484, then subtract this from 389487, giving the answer of 3.

How to Use a TI-30XA

The TI-30XA is a scientific calculator with many functions. You can calculate problems with fractions and decimals, as well as solve problems of probability and functions. A scientific calculator computes the number sentence you type in using the order of operations: parentheses first, then roots and exponents, then division and multiplication and, finally, addition and subtraction.

Instructions

- How to Use a TI-30XA
- 1
Press the [ON/C] key to turn on the calculator. Press the [OFF] key to turn it off. To use the calculator in solar mode, put the solar panel in the light and then press the [ON/C] key. To turn it off when in solar mode, slide the calculator cover back on and it will automatically shut off.

- 2
Replace the batteries by first removing the cover and placing it face down. Use a Phillips-head screwdriver to unscrew the back panel. Remove the back panel and change the batteries. Screw the back panel back on. Press [OFF] [ON/C] and [ON/C].

- 1

Use the basic operation keys for addition [+], subtraction [-], multiplication [x] and division [/]. To change the signs of your values from positive to negative or vice versa, press the [+ -] key before the numbers you enter. Use the parentheses, [(] and [)], to command the calculator to solve what is inside the parentheses first. Press the [=] to solve the number sentence you entered into the calculator.

Find percents of a number by first typing in the number, then [x], then the percent number, [2nd], [%] and, finally, [=]. The [2nd] key allows you to use the commands that are written above each key. For example, to find 20% of 100, type in 100 [x] 20 [2nd] [%] [=] and the display will show the answer, 20.

Turn decimals into fractions by entering the decimal value, then pressing the [2nd] and [F D] keys, then [=]. Turn the fraction back into a decimal by pressing [2nd] and [F D] again. For example, to turn 0.5 into a fraction, type in 0.5 [2nd] [F D] [=].

Turn mixed numbers into improper fractions by entering the mixed number first. Type in the whole number, then the [a b/c] key, then the numerator, the [a b/c] key again and the denominator. Next, press [2nd] [d/c] [=], and the calculator will convert your mixed number into an improper fraction. Press [2nd] [d/c] again to turn it back into a mixed number. For example, to turn 1 1/2 into an improper fraction type in 1 [a b/c] 1 [a b/c] 2 [2nd] [d/c] [=], and the display will show the answer 3/2.

Switch the notation setting of the calculator between engineering, scientific and floating. To select scientific notation, press the [2nd] and [SCI] keys; this will display your answers in scientific notation as a number between 1 and 10 to a power of 10. Press [2nd] [ENG] to switch to the engineering setting; this setting displays values as a number with an exponent that is a multiple of 3. Press [2nd] [FLO] to switch to the floating setting. This is considered standard notation and will display the answer as a standard number.

Use the left arrow key to go back and delete numbers to the right of the cursor that you typed into the display. This must be done before you press [=]. To clear the screen, values and operations, press [ON/C] and [ON/C] again in battery mode, or [CE/C] and [CE/C] again in solar mode.

Hope it helps your problem. Thanks!

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/%]

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

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.

This is a markup on price procedure. The formula is as follows:

Markup%=(Markup Price-Cost)/(Markup Price)

Subtract 10%: 200 [×] 10 [%] [-]

If your calculator is more of an adding machine it works a little bit differently than a calculator. For an example: 10 + 5 - 2 on your machine do the addition of 10 + 5, then to subtract the 2 press 2 then the minus sign to get the total of 13. I hope this is helpful.
