jojo has 40 bananas and she wants to give them to her 36 frends how many dos she have left
at first you would think 4, but if we do tan-1 (sin(40) - cos{36)) we get - 9.43, now we take that and add both 40 and 36 from to it :
(-9.43+40)-(-9.43+36) we get 4, and as to tackle the problem from its roots we root it giving us 2, jojo has 2 banans, 3 if she has a boyfriend/husband
