... However, the table for multiplication is a bit more interesting. There is obviously a row with all zeroes. But in each of the other rows, every value is there and there is no repeated value. This does not always happen; for example, if we wrote down the table for modulus 4, then we would see only ev ...

... The symbols of binary numbers are called bits instead of digits. 1. Each bit is an integer number from 0 to 1; a bit only has 2 possible values, 0 or 1. 2. Each bit is multiplied by a power of 2, depending on its bit position in the number. Binary numbers are used in digital logic because each bit o ...

... • With 8 bit exponent range would be –128 to 127 • Note: -1 would be 11111111 and with simple sorting would appear largest. • For this reason, we take the exponent, add 127 and represent this as unsigned. This is called bias 127. • Then exponent field 11111111 (255) would represent 255 - 127 = 128. ...

You divide 19 by 10 repeatedly until the quotient is 0, same as binary! In fact, the dividing process is just an efficient way to get the coefficients. How d ...

Arithmetic

Arithmetic or arithmetics (from the Greek ἀριθμός arithmos, ""number"") is the oldest and most elementary branch of mathematics. It consists of the study of numbers, especially the properties of the traditional operations between them—addition, subtraction, multiplication and division. Arithmetic is an elementary part of number theory, and number theory is considered to be one of the top-level divisions of modern mathematics, along with algebra, geometry, and analysis. The terms arithmetic and higher arithmetic were used until the beginning of the 20th century as synonyms for number theory and are sometimes still used to refer to a wider part of number theory.
