Sample Problem
A.
5 + 6 x 10 =
B.
(5+6-7)-3^2 =
C.
(11/44)4 =
D.
1^9 + 1^9 + 1^9 =
E.
(30 x 30)^3 – (15/5)^5 =
Solution
A.
5 + 6 x 10 =
11 x 10 =
11 x 10 = 110
B.
(5+6-7)-3^2 =
(11-7)-9 =
(4)-9 =
4-9 = -5
C.
(11/44)4 =
(1/4)4 =
1/4 x 4 = 1
D.
1^9 + 1^9 + 1^9 =
1 + 1 + 1 =
1 + 1 + 1 = 3
E.
(30 x 30)^3 – (15/5)^5 =
(900)^3 – (3)^5 =
729,000,000 – 243 = 728,999,757
