Find the right combination
The computer chose a secret code (sequence of 4 digits from 1 to 6). Your goal is to find that code. Black circles indicate the number of hits on the right spot. White circles indicate the number of hits on the wrong spot. Calculate the number 564
NUMBERMANIA: Calculate the number 564 using numbers [8, 3, 6, 2, 64, 932] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once. Find number abc
If c71bc + 2b844 = b4aa7 find number abc. Multiple solutions may exist. 
English lessons
A missionary suddenly realizes that the one thing he hasn't yet taught the natives he serves is how to speak English, so he takes the chief for a walk in the jungle.
He points to a tree and says to the chief: "This is a tree." The chief looks at the tree and grunts: "Tree."
The missionary is pleased with the response. They walk a little farther and the missionary points to a rock and says: "This is a rock."
Hearing this, the chief looks and grunts: "Rock."
The missionary is really getting enthusiastic about the results when he hears a rustling in the bushes.
As he peeks over the top, he sees a couple of the natives in the midst of heavy sexual activity. Flustered, the missionary quickly says to the chief: "Riding a bike."
The chief looks at the preoccupied couple briefly, pulls out his blowgun and kills them.
The missionary goes ballistic and yells at the chief that he has spent years teaching the tribe how to be civilized and kind to each other.
"How could you kill these people in cold blood that way?" he demands.
"My bike," the chief replies.

John WrottesleyDied 27 Oct 1867 at age 69 (born 5 Aug 1798).John Wrottesley, 2nd Baron Wrottesley, was an English astronomer, who published Catalogue Of The RA Of 1318 Stars. He was a founder member of the Royal Astronomical Society. From his first Observatory in Blackheath, London, he recorded over 12,000 observations. After he inherited the title and the Staffordshire family estate at Wrottesley in 1841, he built an observatory there. In 1855, the city of Wolverhampton nearby decreed that if any ... furnace chimney ...was built ... within three miles of the observatory, it shall be constructed on the best and approved principles “for consuming the smoke arising ... therefrom.” This of course was so that observations from the observatory would not be hampered by smoke pollution. |

NUMBERMANIA: Calculate the number 2708 using numbers [2, 1, 8, 2, 11, 904] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once. MAGIC SQUARE: Calculate A+B+C
The aim is to place the some numbers from the list (9, 10, 14, 24, 25, 29, 34, 37, 65, 66, 70) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A+B+C.
