Hi theonlyone24

One way to look at it is:
Meg bought a chocolate for 3.75
Poor Meg could not count the money
So, she gave the lot as paymnet
Cash Register returned 4.89

Another solution
Meg did not have 8.64 (in Australia there is no 1c, 2c,3c, 4c)
and she did not get 4.89 ( the same explanation - there is no 9c, money is rounded up or down to the nearest multiple of 5

Subtracting monomials

Hi there,

Remember that the SHARP calculator does not solve algebra.
But some tips for adding and subtracting monomials include:
Group all the terms that are like terms (they have the same variables and exponents. Make sure that you move them with the sign in front of them (dont lose your minuses).
Add or subtract just the numbers in front of the terms and leave the variables exactly as they are when you write down the answer.

I m usinf casio fx-300 Es calculator. is it possible to do polar addition or subtraction without changing to rectangular form?

No you cannot. An ordered pair made up of a radius and an angle is a vector. And you do not add nor subtract vectors as you would scalar (non vector) values.

2.45.35 hours - 0.23. 12 hours = ?. a short quick method please

Seconds: Subtract 12 from 35 to get 23.
Minutes: Subtract 23 from 45 to get 22
Hours: Subtract 0 from 2 to get 2.

Put the three together to get 2.22.23

This one was easy because there was no need for carry. If you do have to carry, just make sure you carry 60. Otherwise, it's exactly the same as when you learned subtraction in second grade.

Some calculators have conversions between decimal degrees/hours and degrees/hours:minutes:seconds. If you have such a calculator, you can convert both numbers to decimal, subtract, and convert back. Since you didn't specify what calculator you have, I can't tell whether this is an option for you.

How do subtract on this calculator

To calculate 7-2=5 (for example) on a business calculator:
7 + (all positive entries are followed by the + key)
2 - (all negative entries are followed by the - key)
* (The Total key, marked with a star or a T finishes the calculation.)

It seems strange to people who use handheld calculators, but this is how adding machines have worked since the days of hand-cranked adding machines. The subtotal key (marked with S or a diamond) prints the running total without clearing it back to zero.

My calculator will add, but after my total and then I want to subtract, it subtracts by the number I added.

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.

I cant figure out how to be able to take a fraction and subtract it to another fraction on my TI-84 PLUS calculator

Given two fractions a over b and c over d, you can subtract the first from the second by entering
( c / d ) - ( a / b ) ENTER

The calculator will give you a decimal result, which you can (probably) convert back to a fraction by using the >Frac command. Press MATH 1 ENTER

I am unable to subtract

The way to do math on this calculator is a bit different than on others. To start off, when doing subtraction, you must press the + key. This tells the calculator that you are working with a positive number.

Say you have $588.43 in you check book but you spent $136.92. The buttons you press on the calculator will be as follows:

588.43 + 136.92 -

The positive total of 451.51 will be on your screen. If you are using the print function as a way of keeping track, press # to print the on screen total.

Just remember, enter your first number and hit +. After this, each number that you are subtracting will have a - behind it.

How do I add and subtract on this thing?

I do know what calculator you have but on most calculators you have digit keys to key in numbers, operation keys (multiplication, division, addition, subtraction), function keys (log, exponential, %, square root, square or a power) and you have the = key to obtain the result of the calculation.

Press the [ON] button

To add 2 numbers, exemple 12 and 13
12 [+ key] 13 [= key]. Calculator displays 25, or 25.00 or 25.0000...

To subtract
13 [- key] 7 [=key] . Calculator displays 6 or 6.00, 6.0000....

To multiply
32 [x key] 5 [= key]. Calculator displays 160.

You may have memory keys, to store values. They may be labeled M to enter a number in memory, M+ to add a number to the one already in memory, M- to subtract from the number already in memory.

Hope it gets you started.

How do you subtract on this calculator? if I do 10 minus it puts that minus in front of 10 and it can not subtract?

Its a little strange. Suppose you want subtract 10 from 38. Do this:
Enter 38 press plus key.
Enter 10, press minus key.
Press the equal sign. You will have the result.
