RECURSION ON COUNTING |
replace tedious TALLYING CARDINATION by COUNTING - thus, |||| Þ 4 - GENERATED BY RECURSION: INITIAL COUNT, 0 -- RECURSION BY SUCCESSOR OPERATION, S( ) , s. t., FOR ANY COUNT n , S(n) º n + 1 , where n + 1 is SUCCESSOR of n - thus, S(0) = 1 -- S(1) = 2 -- S(2) = 3 - COUNTS ARE "NATURAL NUMBERS" - EVERY NATURAL NUMBER HAS SUCCESSOR so SUCCESSION IS A TOTAL OPERATION -- SUCCESSOR INDUCES INVERSE OPERATION, PREDECESSOR, P( ), s. t. n is PREDECESSOR of n + 1, i.e., P(n + 1) = n IF,AND ONLY IF, S(n) = n + 1 -- HOWEVER, 0 HAS NO PREDECESSOR, so P( ) IS A PARTIAL (NOT A TOTAL) OPERATION. |

RECURSION ON COUNTS FOR
COMBINING |
A CHILD COUNT OFF 3 FINGERS, THEN 4 FINGERS, & COMBINES TO COUNT OFf THE 7 FINGERS - SUCH TEDIOUS COMBINING IS REPLACED BY ADDITION CONSTRUCTED BY RECURSION ON COUNTING OPERATION: S(a) º a + 1, a + S(b) º S(a + b) - AS WITH COUNTING, ADDITION ALWAYS YIELDS A NATURAL NUMBER, SO ADDITION IS A TOTAL OPERATION - PARTIAL LIMIT ON "COUNTING BACKWARDS" PUTS LIMIT ON INVERSE OF ADDITION: SUBTRACTION - BUT (NOTED ELSEWHERE) MORE THAN INDUCTION ON ADDING IS NEEDED TO DEFINE ITS INVERSE. |

RECURSION ON ADDENDS FOR

REPEATED DDITION, SUCH AS 5 + 5 + 5 + 5 IS TEDIOUS -- BYPASSED BY DEFINING MULTIPLICATION AS RECURSION ON ADDITION: a * 1 º a, a * S(b) º a * b + a - LIKE COUNTING AND ADDITION, MULTIPLICATION IS TOTAL, ALWAYS YIELDING A NATURAL NUMBER - BUT PARTIAL LIMITS ON INVERSE OF COUNTING AND INVERSE OF ADDITION PUT SUCH A LIMIT ON MULTIPLICATION. |

RECURSION ON PRODUCTS FOR

REPEATED MULTIPLICATION OF FACTORS, SUCH AS 4*4*4*4 IS TEDIOUS - BYPASSED BY DEFINING EXPONENTIATION, DENOTED be = p, WHERE b IS BASE, e IS EXPONENT, p IS POWER (eTH POWER OF b), DEFINED RECURSIVELY BY MULTIPLICATION: b0 º 1, bS(e) º (be)*b -- LIKE COUNTING, ADDITION, MULTIPLICATION, EXPONENTIATION IS A TOTAL OPERATION - BUT LIMIT ON INVERSE OF, RSP., COUNTING, ADDITION, MULTIPLICATION, PUTS LIMIT ON INVERSE OF EXPONENTIATION. |
