What is 110 as a decimal?
The person below explains binary base well, but I think they made a mistake of starting the base at the value of "1"; when all the bases should start at the value of "0". So in base 2 it goes from 0,1,2,4,8,16,32... (it doubles with every increment except when at zero). Now see the answer below and the value of 110 should be 3 (110 =1X2 + 1X1 + 0X0 = 3 ≠ 6. Well, 110 IS a decimal number. However, assuming "110" is a binary or base 2 number, then 110 = 1x4 + 1x2 + 0x1 = 6. When stating a number not in base ten or decimal form, the base needs to be stated. So you would say "110 binary" = "6 decimal". Binary is usually considered a computer term as they all 'compute' using binary numbers. However there are other related bases used for Human convenience such as "octal, base 8", and "hexadecimal, base 16". Hexadecimal is the preferred base as it represents a more "shorthand" method of specifying numbers compatible with computer semantics. An example: the number 65535 decimal = 1111111111111111 which is stored as two bytes as binary 11111111, 11111111 or 16 bits. In base 16, hexadecimal, this is more easily written as "FFFF" or more formally in programming as "0XFFFF" where the "0X" prefix denotes hexadecimal or base 16. Since one byte = 8 bits = 256 numbers, and 4 bits = 16 numbers, one byte uses two hexadecimal digits with a value of "00" through "FF" which is zero through 255 decimal, or 256 total numbers. As far as "base", binary is base 2 meaning only two digits are used: 0 & 1. Decimal is base 10 and means ten digits are used, zero through nine. Hexadecimal is base 16 and means 16 digits are used. However, since we only have ten digits in our numeric decimal system, letters are used as additional digits and the sequence used is 0,1,2,3,4,5,6,7,8,9,A.B.C.D.E.F allowing 16 "digits" instead of the normal 10. Always specify the base of a number if it is not decimal so people know what the number really is.

Numbering system that has just two digits 0 and 1?
Binary Bi means two 1 and 0 thers your two numbers don't forget zero is counted ; If you put 3 binary numbers together you get Octal (for eight) 111 the right most one is for one the middle is 2 the left is 4 so 111 = 7 highest number in octal , now move up to what most people think of in computers is Hexadecimal 1111 or groups of 4 binary starting from the right ,1,2,4 then 8 so 1111= 15 or F ; 10(a) thru 15(F) are represented by letters FF=255 pretty cool !! in binary you double the number each time 1,2,4,8,16,32.64.128,256,512,1024,2048,4096 now you know why ram comes in these sizes....... its binary baby!!

How does ten equal two?
5 multiplied by 2 is 10 Answer: Consider the joke: There are 10 kinds of people in the world those who understand binary and those that don't. Binary uses powers of 2 to express numbers. Thus 20=1,21=2, 22=4 and so on (numbers shown in decimal). This is expressed as strings of numbers using either 0 or 1. Thus 0(binary) =0 (deciamal). 1(Binary)=1 (decimal) or 20, 10(binary)=2(decimal) or 21, 11=3 (decimal) =10+1(binary) = 21+20 and so on.

3 ways people dealt with numbers in ancient times?
The Babylonians used base 60 (hexadecimal) instead of our base 10 (decimal) or base 2 (binary). The Romans used a complicated scheme using I, V, X, C, D and M. This severely impeded their ability to do arithmetical calculations. Arabic scholars invented the idea and usage of zero, leading finally to what became our modern system.

What are base8 binary numbers?
No such animal. Binary numbers are base 2. Base 8 numbers are called octal. . Confusion arose because in the early days of computers hardly anyone was used to binary. A particular difficulty came from the sheer length of a binary number compared to its decimal equivalent. A number in the range 8,000,000 to -8,000,000 is easy to read, say and understand. A 24 bit (binary) word, enough for +/- 8,000,000 is too much for people to take in. . So, a 24 bit word was split into 8 groups of 3, just by spaces in between. It was not difficult to remember that 110 was 6 or 101 was 5. The 3-bit groups were spoken in their octal equivalents, written down like that, and easily used to enter a 24 bit word onto a set of switches in binary. The programmer's 'cheat-sheet' for machine code was printed like this in the octal names for 3 bit groups. Programmers who work in assembler (almost machine code) still use a trick like this. However, word lengths today are not divisible by three; great lengths of binary are split into groups of four, which are then treated as hexadecimal. When you see a page or more looking like: - 00 00 37 53 6F A0 39 FF 8C 00 CB DB 52 22 00 that is hex.

How do you add and subtract the binary number system?
You do it exactly like decimal subtraction, and when needed you borrow from the next higher place digit, however remember you borrow 2 everytime and not 10. Some people convert the two binary numbers into decimal, do the subtraction and then convert the result back to binary. Following is an example of binary subtraction. 1001 0110 ____ 0011 ____ I started explaining the borrowing process in words but it gets confusing. Please relate it to the borrowing process in decimal.

Why do people use decimal instead of binary?
We have ten fingers (including thumbs) and early counting is based on one-to-one mapping onto these digits. So one reason is simple familiarity. The other advantage of counting in decimals is that fewer digits are required: 4 decimal digits takes you to over a thousand, you would need 10 binary digits to go over 1024. It gets worse with larger numbers: 7 decimal digits to go over a million but 20 binary digit. I have phones with 11 digit numbers (without the international country code). In binary, that would be a 33-digit number. No thanks!
Asked in Computer Programming
Why do computer designers use the binary code to represent information?
Computer designers use binary format to represent information. When we speak of code, we are usually talking about the instructions in the programs themselves. In an electronic computer, information has to be stored electronically. This is done by using transistor switches that can be thrown electronically to a desired position, on or off, and read later. Each piece of information stored this way is a binary digit, and the values that can be assigned to it are 0 or 1, represented by the switch being off or on. This binary digit is called a bit. The digits can be combined into binary values of any length, but the commonly used length is eight bits, which is a byte. When information is stored in computer memory, it is usually in bytes or groups of bytes, with the individual bytes having address that can be accessed by numerical value. The bits are usually represented using hexadecimal format, which is easily translated from binary and much easier for most human beings to handle. The numerals for this are 0 through 9 plus A through F, making 16 values. For people accustomed to decimal, this seems very cumbersome. But trying to work with computers in decimal at the level of the instructions themselves is sufficiently difficult that most experienced people don't try.
