Octal (base 8) is a numeral system with eight as the base. In the decimal system, each place is a power of ten. For example: = ...
"A base is a natural number B whose powers (B multiplied by itself some number of times) are specially designated within a numerical system." [1]: 38 The term is not equivalent to radix, as it applies to all numerical notation systems (not just positional ones with a radix) and most systems of spoken numbers. [1]
For example, the base-8 numeral 23 8 contains two digits, "2" and "3", and with a base number (subscripted) "8". When converted to base-10, the 23 8 is equivalent to 19 10 , i.e. 23 8 = 19 10 . In our notation here, the subscript " 8 " of the numeral 23 8 is part of the numeral, but this may not always be the case.

The positional systems are classified by their base or radix, which is the number of symbols called digits used by the system. In base 10, ten different digits 0, ..., 9 are used and the position of a digit is used to signify the power of ten that the digit is to be multiplied with, as in 304 = 3×100 + 0×10 + 4×1 or more precisely 3×10 2 ...
Bases on balls are not counted in calculating batting average. This is part of the reason OBP is now regarded by "figger filberts" as a truer measure of a hitter's worth at the plate. In 1887, there was an experiment with including bases-on-balls as hits (and as at-bats) in computing the batting average.

The only base-4 repunit prime is 5 (). = (+) (), and 3 always divides + when n is odd and when n is even. For n greater than 2, both + and are greater than 3, so removing the factor of 3 still leaves two factors greater than 1.
