7 + (4^2 + 5) x 2 = 51
(2 + 3) x 3^2 + 39 / 3 = 54
2 x [(4 + 3) x 5 - 6] = 58
[84 / (3 + 4)] x 3 + 1 = 37
Therefore none of them equal 52!
A just trust me :-> if your wrong I’m sorry :
The median is the middle number in a sorted, ascending or descending, list of numbers.
0, 0, 1, 1, 1.5, 1.5, 1.5, 1.5, 2, 2, 2, 2, 2.5, 2.5, 3, 3, 3, 3, 3, 3.5, 3.5, 4, 4, 4, 4.5,
Therefore, the median would be 2.5 hours.
