@hicasamadim Simple, the recurring values are added and the value is multiplied by the recurring value. e.g.( 2+2)**2 = 8. Similarly. (6+6)*6 = 72.
72 is the answer.
@Indemosyd Wrong, Africa is rich. In fact, Africa can fit 100's of them in the equation. So next time think deeper of what A continent means. Africa ain't a small fish to fry by a thought. #africaisourbusuness.
