Document Summary

Number unit of an abstract mathematical system subject to laws of arithmetic. Natural number number 0 and any number obtained by recreantly adding 1 to it. Negative number value less than 0 with assign opposite to positive counterpart. Rational number integer or quotient of two integers *division by zero excluded. Integer natural number, negative of natural number and 0. Base foundational value of number system, which dictates number of digits and values of digit positions. Magnitude base raised to its exponent; determined by multiplying magnitude of column by digit in column and summing products. Base-2 (binary) number system 0, 1. Byte x8 (word group of one or more bytes; number of bits in word is word length) 10 cannot represent ten because it is + 16 in hexadecimal. Fixed length notation system: have to decide how many bits to use. 8 + 4 + 2 + 1 = 15 (unsigned value)
