A number when doubled means it has been multiplied by 2.
0 x 2 = 0 : 1 x 2 = 2 : 2 x 2 = 4 : 3 x 2 + 6 : 4 x 2 + 8 : 5 x 2 + 10
6 x 2 = 12 : 7 x 2 = 14 : 8 x 2 = 16 : 9 x 2 = 18 : 10 x 2 = 20
11 x 2 = 22 : 12 x 2 = 24 : 13 x 2 + 26 : 14 x 2 = 28 : 15 x 2 = 30
16 x 2 = 32 : 17 x 2 = 34 : 18 x 2 = 36 : 19 x 2 = 38 : 20 x 2 = 40
