what is the usage of basic numbers?(sth. like in computers??!!)?

Base numbers are used to "encode" the value of an integer into a workable space. When you think about it, a number really represents how far away it is from zero on the number line.\n\nWithout some form of encoding we'd have no easy way to represent these numbers. For example, in base 10, I can represent every integer from zero to just under one million using only 6 digits.\n\nPeople used numbers before our current method of encoding was developed. Consider Roman Numerals. They represent integers, but they have several problems. Their encoding scheme starts to wear out around a million, and it's next to impossible to do basic arithmetic operations with them.\n\nOnce people figured out how to use bases to encode integers, the base number 10 seemed like a pretty good choice. Most languages count in groups of 10 and people have 10 fingers.\n\nThat was pretty much it until people started building computers. There was no easy way to represent the digits from 0 to 9, but there was an easy way to represent the digits 0 and 1. The "bit" was either off or on. This could be rendered by an electrical circuit being on or off.\n\nBy stringing a set of these bits together, engineers figured out to to arrange them to do arthimetic. However, there was one problem. Since the digits where only ones and zeros, the numbers being represented were in a binary representation - or more consistenly put - they were in base 2, because there were only two digits in this encoding system.\n\nLooking a string of zeros and ones gets confusing. While the encoding works, it's tedious for people to do it. Engineers started to cluster the bits together in groups of 3 bits and 4 bits to make it easier to read. There are 8 ways to represent 3 bits and 16 ways to represent 4 bits.\n\n3 bits grouped together are represented by the digits 0 to 7. This is also the same as a base 8 encoding system, also called octal. So there's a very simple mapping between 3 bits and octal.\n\n4 bits grouped together are represented by the "characters" 0-9 followed by A-F. These letters are considered numbers in this representation. This grouping is a base 16 encoding system, and it's called hexadecimal.\n\nEngineers who deal with hardware and device drivers can probably think in octal and hexadecimal, but most of us can't.\n\nSo why don't we use base 10 in computer engineering? Because, it doesn't map to binary. Not all of the bits would be used as they are in octal and hexadecimal. But calculators and computers don't seem to use binary, octal or hexadecimal. Oh, but they do. They just do it "under the hood." Before the answers are shown to you, they're converted into decimal form, so you can understand them easily.\n\nTrust me. Computer Science Circuit Design classes would be a whole lot easier if people were like cartoon characters and only had a total of 8 fingers.

use the number line concept

The difficult thing here is reading and writing the numbers. They must be transformed from ASCII and then the result transformed back to ASCII.I found a program that calculates the sum of 2 numbers.I hope it helps.

Are we counting the number of times the digit zero appears?  For example, would 1,000,000 result in 6 zeroes?  If so, you can count the zeroes as follows:\n\nFirst, count the numbers of the form nnnnnn0... 10, 20, 30, ..., 100, 110, 120, ..., 999990, 1000000.  Every 10th number will have this form, so that is 100,000 zeroes in the units place (don't count zero, but do count 1 million).\n\n1,000,000 * 1/10 = 100,000\n100,000 - 1 + 1 = 100,000\n\nNext, count nnnnn0n... 100, 101, 102, 103...  109, 200, 201, 202, ... 209, .... 999900, 999901, 999902, ..., 999,999, 1,000,000.  This would be 10 out of every hundred numbers, so that is 99,991 zeroes in the tens place.  (You don't count 0 to 9), but you do count 1 million.\n\n1,000,000 * 10/100 = 100,000\n100,000 - 10 + 1 = 99,991\n\nNext, count nnnn0nn.  This would be 100 out of every thousand numbers, but not counting 0 to 99, but counting 1 million.  So that is 99,901.\n\n1,000,000 * 100/1000 = 100,000\n100,000 - 100 + 1 = 99,901\n\nNext, count nnn0nnn.  This would be 1000 out of every ten thousand numbers, but not counting 0 to 999, but counting 1 million.  So that is 99,001.\n\n1,000,000 * 1000/10000 = 100,000\n100,000 - 1,000 + 1 = 99,001\n\nNext, count nn0nnnn.  This would be 10000 out of every hundred thousand numbers, but not counting 0 to 9999, but counting 1 million.  So that is 90,001.\n\n1,000,000 * 10000/100000 = 100,000\n100,000 - 10,000 + 1 = 90,001\n\nFinally, count n0nnnnn.  Without a leading digit, none of the numbers except 1 million would have this pattern:\n\n1,000,000 * 100000/1000000 = 100,000\n100,000 - 100,000 + 1 = 1\n\n100,000 + 99,991 + 99,901 + 99,001 + 90,001 + 1 = 488,895\nSo the answer is that the digit zero appears 488,895 times in the numbers from 1 to 1 million, inclusive.

if you just want to add a few numbers and are on windows go into the start menu->programs->accesories and there should be a calculator program for you to use

Well it stores its data as 1s and 0s. Thats all how a computer works. It runs all on 1s and 0s. If you hit the keyboard you might be telling it to type the letter "H" but it sees it as 11001111 (not really the right code). Its the same way a chip works. It sees everything it stores as 110011101010101011010101010.

it's the numbers that represent every charater that can be inputted on a computer.  you can see the list here\n\nhttp://www.lookuptables.com/

Are you able to use any other numbers and operators?  If so this would be fairly easy.  Using only Three 8's and a subtraction symbol it is not possibe\n\nClosest example (8+8)/8-1=1

everything that interprets 1s and 0s into something you can use is an operating system, the difference is the architechture, ex:windows is x86

How does this work?  Is it okay to have a decimal in the middle?\n\nType 1   (Screen says 1)\n/ 3          (Screen says 0.3333333)\nx 3         (Screen says 0.9999999)\n+ 9        (Screen says 9.9999999)\n\n- Jack

Numbers 1 - 9 are spelled out, once you get to10 and above, you can just use the numerals. Here's a web site to prove my point...\n\nhttp://www.grammarbook.com/numbers/numbers.asp

I'm a bit rusty with BASIC but both of them look ok (assuming the syntax is good).\n\nThe second one is more efficient because of the FOR loop.\n\nIf you always need to calculate the average for 6 students then you don't need to prompt for the number of students, although it does make the program more useful.

A computer is an information-processing machine that works by converting all kinds of information into binary numbers (ones and zeros) and then using simple mathematics to make decisions about, or to rearrange, those numbers. There are two things essential to understanding the basics of how a computer works. One is that a computer treats any type of information (not only numbers but also letters, words, dates, and so on) as if it consisted simply of binary ones and zeros. For example, a computer can translate the letter “A” typed into its keyboard into a string of ones and zeros, such as 1000001. One reason to do this is that once in binary form, the information can be stored and moved about more easily.

My guess is that you are trying to use this method to find out if  a character is a letter or a digit. The name of the method is wrong. and the wya you are using it might be wrong too. It is Character.isLetter(...) or Character.isDigit(...) Hope that helps\n\n\nChiney

look at a few examples and it will make sense\n\nfor example \n\n02 (where the 2 is small)   -> _ O    (the _ is where a number goes)  (2)
