Answer 1

from itertools import permutations, product

def acronyms(x):
    res = {x}
    for digs in permutations(str(x)):
        if digs[0] != '0': # число, если не ноль, не начинается с нуля
            res.add(int(''.join(digs)))
    return res

a, b, c = 54, 12, 75
zz = acronyms(c)
for x, y in product(acronyms(a), acronyms(b)):
    if x + y in zz:
        print("%d + %d = %d" % (x, y, x + y))
