A) STARTED WITH EQUATOR	B) STARTER WITH NORTH POLE	C) STARTER WITH SOUTH POLE	D) STARTER WITH 80 DEGREE NORTH POLE	E) STARTER WITH NORTH OF SOUTH POLE
Let x = the latitude sought.   Then marking the northings +, and the southings -;   By the statement x + 4 - 13 + 17 - 19 = -11   STARTED WITH EQUATORnd x = 0.
