ADD_CONV : conv
STRUCTURE
SYNOPSIS
Calculates by inference the sum of two numerals.
LIBRARY
reduce
DESCRIPTION
If m and n are numerals (e.g. 0, 1, 2, 3,...) of type :num, then ADD_CONV ``m + n`` returns the theorem:
   |- m + n = s
where s is the numeral that denotes the sum of the natural numbers denoted by m and n.
FAILURE
ADD_CONV tm fails unless tm is of the form ``m + n``, where m and n are numerals of type :num.
EXAMPLE
> ADD_CONV ``75 + 25``;
val it = |- 75 + 25 = 100 : thm
