Same sort of thing happens in other bases for the reciprocal of (100 - 3) expressed in … While the primality of a number does not depend on the numeral system used, truncatable primes are defined only in relation with a given base. A variation involves removing 2 or more decimal digits at a time. This is mathematically equivalent to using base 100 or a larger power of 10, with the restriction that base 10 digits must be at least 10 , in order to match a decimal n-digit number with no leading 0.
