The equations in Questions 1 and 2 above used different numbers and different math operations. BUT why did they both have the same answer?
B/c question 1 used the multiplication operation so our final answer had to be larger than 5.55 but question 2 used the division operation so our final answer had to be smaller than 555,000, which made both of the answers be 5,550
