Question

6666-(66:6+a-6666:6+666:6)x 6 = 666

Answer 1

(66:6+a-6666:6+666:6)x6=6666-666
(66:6+a-6666:6+666:6)=6000:6
(11+a-1111+111)=1000
11+a-1111=1000-111
11+a=889+1111
a=2000-11
a=1989

Answer 2

66:6+a-6666:6+666:6)x6=6666-666
(66:6+a-6666:6+666:6)=6000:6
(11+a-1111+111)=1000
11+a-1111=1000-111
11+a=889+1111
a=2000-11
a=1989
