Re: Percentage of a Number ?Hi; So you say about 45.5% Or do you want the percentage reduction? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20131111 03:51:43
Re: Percentage of a Number ?Subtract 2345 from both sides. Divide both sides by  2345. You get .5449893390191898. So you would need a 54.49893390191898% reduction.

Re: Percentage of a Number ?54% is not the correct answer that I gave you. In mathematics, you don't understand things. You just get used to them.

Re: Percentage of a Number ?I never said that was the correct answer you gave me ! <sigh> #8 20131111 17:43:56
Re: Percentage of a Number ?
You are missing what I am saying. 54% is not the answer I gave you, you have rounded off the correct answer.
Nope, I am not saying any of that. First of all where do you get 54% from? I am saying if you take a 54.49893390191898% reduction you will come out with 1067 ( a number very close to it!).

Re: Percentage of a Number ?It is not 54, it is 54.49893390191898 %. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Percentage of a Number ?I never said to round in the calculation.
That was just for convenience. If I were speaking that I would say about 45%. But in a calculation if you use a number that you say is about this then the answer is rounded also. That is why you are getting 1266.3 not 1278. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Percentage of a Number ?
The above statement is incorrect and in math correctly stating the problem is the difference between solving it and not solving it. You can not subtract 45% from 2345. You can subtract 45% of something from 2345. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Percentage of a Number ?If I get 45% off that is the decimal .45 If I get 54.49893390191898 % off that is the decimal .5449893390191898 In mathematics, you don't understand things.

Re: Percentage of a Number ?The dot between the .45 and the 2345 means multiply. It can also be written, In mathematics, you don't understand things. You just get used to them.

Re: Percentage of a Number ?That's because you are doing subtraction before multiplication. When there are no parenthesis, you do multiplication before addition and subtraction. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #22 20131112 21:35:20
Re: Percentage of a Number ?Many calculators, particularly scientific calculators (eg, M$oft's scientific calculator), will automatically do the operations in the correct order (BODMAS) without needing to use parentheses, but simpler calculators (eg, that same M$oft calculator set to the 'Standard' option) usually won't.

Re: Percentage of a Number ?
One problem at a time. Do you understand the percentage we are talking about? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
