2*12 = 2*1 = 2
2/4 raised to the second power equals 0.25
1 1/2 is 3/2 so multiply it by its reciprocal, which is 2/3, and it equals 6/6 or 1.
2 to the power of 2 is NOT the second Mersenne number. The second Mersenne number is 3, derived from the Mersenne algorithm 22 - 1 = 3.

2 X 11 = 22
2 x 3 = 6
(1-2/3) x (2-1/5) = (5/3) x (11/5) = (55/15) = 11/3 = 3-2/3

1^2 = 1X1 = 1 ft
(1/6)2 = 1/36
1/4 (1/2) squared = 1/2 x 1/2 = 1/4
