Document Summary

-natural numbers: zero and any number obtained by repeating adding one to it. -integers: values that are either a natural number or negative number. -rational numbers: values that are integers or quotient of two integers. -magnitude of number is determined by multiplying magnitude of column by the digit in. -from left to right, left side number is most significant and right side number is least. - n based unsigned integer in base b . D_n-1 b^n-1 +d_n-2 b^n-2 ++d_i b^i +d_^1 b1 +d_0 b^0. -decimal is base 10 ans has 10 digit symbols. -binary is base 2 and has 2 digit symbols. -for a value to exist in given base, can only contain digits in that base, which range from. Positional notation: the column and summing the products significant. 0 up to, and not including, the base. -number of bits in a word determines the word length of computer, which is usually a.
