Because of the minus sign, 8 turns to -8, -8x3=-24.
2x x 2x x 2x = 8x3
73 = (7 x 101) + (3 x 100)
73 = |- (sqrt(9!))/9 -| + 9 - sqrt 9 [ceiling]= |_ sqrt sqrt sqrt sqrt sqrt sqrt sqrt 139! _|{the rounded-down 128th-root of 139!; since we can make 139 with fournines, this gives us another way to make 73 with four nines}Another option that you may find is simpler:Noting that 9 to the power zero equals 1, then:73 = (9 x 9) - 9 + 9 0= 81 - 9 + 1 = 73
