There is a serious flaw in the "double-equation". 8.6 = 5p - 4p = 2.4
It would imply that 8.6 = 2.4 which is clearly not true.
860 centimeters = 86 decimeters
86-27 equals = 59
86 + 24 = 110
177
It is: 17.2*5 = 86
86 F
6 is a factor of 24 (6*4=24), but 6 is not a factor of 86 (86 / 6= 14 1/3)
86 - 47 = 39
It is: 258/3 = 86
Pi plus 86 equals 89.14
37 multiplied by 86 is 3,182.
86 times 2 equals 172.
