Numbers
Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

Double a number is 3 more than a number?
Asked by Wiki User
Assuming that the question is double a number is 3 more than THE number, let the original number be x then double the number (= 2x) is 3 more than the number (= x+3) So solve 2x = x + 3 Take x away from each side: x = 3

What is binary number system?
Asked by Wiki User
Binary is the major form of communication between computers. Binary Number system consists of only 0s and 1s.
Think of binary as off/on, off is zero, as in nothing, and on is one, as in something.
Binary numbers start with a column with the value of 1 on the right side. The next column, to the left, has double the value (which is 2), the next left doubles again (which is 4), then 8, 16, 32, 64, 128 etc. The inclusion of a number 1 in a column means that the number should be included in the total. The inclusion of a zero in a column means that the number should not be counted. Using just this combination of 1s and 0s any number can be represented. For example...
1 = 1
2 = 10
3 = 11
4 = 100
10 = 1010
15 = 1111
65 = 1000001
To convert the numbers from binary to decimal you can simply use a calculator and starting at the right side of the binary number if the first digit is 1 then add 1 to your calculator. If it is zero don't add anything, move left to the next column, if there is a 1 in this column add 2 to your total on your calculator, if it is a zero don't add anything, continue doing this, doubling the value for each column and adding the number if there is a 1 and ignoring it if there is a zero. For example....
The binary number 1100, starting at the right has 0 in the 1 column, 0 in the 2 column, 1 in the 4 column and 1 in the 8 column, so you would ignore 1 and 2 and simply add 4 + 8, giving your a value of 12, which is correct.
Why is binary number system used in digital electronics?
Asked by Wiki User
Binary is simpler than decimal. And it is easy to represent binary numbers with signals, since only two states are required. For example, a low voltage state might represent a zero, and a high voltage state might represent a one. Or vice versa.

How do you add and subtract the binary number system?
Asked by Wiki User
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 you need different number system when computer work on binary?
Asked by Wiki User
Different number systems are taught, for one, to let you understand the basic concepts. Most number systems, however, will seldom be used. If you work with computers, you will mainly need:
- Base 10, because that is the system we commonly use in "real life".
- Base 2, because that is the system used internally by computers.
- Base 16, often used as a shortcut to express base 2 numbers.
- Base 8 can also be used as such a shortcut, but it is not commonly used nowadays. Base 8 is mainly a relic from the past.

Is it possible for a plus b to be neither positive nor negative?
Asked by Wiki User
If you're insinuating a 'B' plus as a grade, then it should be positive. Anything lower than an 87% I'd fret. For a test grade it's fine, but not so good for a final grade.
Who invented binary number system?
Asked by Wiki User
The modern version of binary numbers was discovered by the German mathematician Gottfried Leibniz in 1679. He credits the invention of binary numbers to Fu Xi, who he claims invented the "I Ching" binary system in China 4,000 years ago. Modern historians believe that the "I Ching", which contains the "bagua" binary hexagrams, dates closer to the 9th century BC. Binary numbers were also used elsewhere in the world outside China and Germany. In Polynesia, indigenous groups used a binary decimal system as early as 1450 AD. Pingala in India used a binary system in 200 BC for prosody. A similar system was used in sub-saharan Africa as part of their numerology system (known as "geomancy"). The sort of binary we use today however was put together by a fellow named "Francis Bacon" , and another chap named "Gottfried Leibniz" in the 1600s. The full power of Binary however was finally unlocked by a man named "George Boole" in the 1800s when he invented Boolean algebra which brought all the ideas together.
