Calculate the number 9071
NUMBERMANIA: Calculate the number 9071 using numbers [9, 9, 2, 9, 58, 928] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once.
Find number abc
If a3a79 + b90cc = c52a90 find number abc. Multiple solutions may exist.
What a winning 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.
Praying and Sleeping
Two men arrive at the Pearly Gates at about the same time, both wanting to know if they will be admitted to heaven. St. Peter asks the first man his name, where he is from, and what he did in life.
The man answers that he is John Smith and that he was a taxi driver in New York City.
St. Peter looks through his book, then gives the man a luxurious silken robe and a golden staff, and bids him welcome into heaven for his eternal reward.
St. Peter then asks the second man the same questions. He replies that his name is Thomas O'Malley, and that he was a Catholic priest in Chicago. St. Peter looks in his book, then gives him a cotton robe and a wooden staff, and bids him to enter into heaven for his eternal reward.
Father O'Malley says, Wait a minute! Why did that taxi driver get a silken robe and golden staff while I, a Catholic Priest and a man of God, got a cotton robe and wooden staff?
St. Peter told him that the rewards in heaven are based on results, and while Father O'Malley preached, people slept, but while John Smith drove, people prayed!
Calculate the number 4491
NUMBERMANIA: Calculate the number 4491 using numbers [7, 5, 7, 4, 47, 946] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once.
Edward WittenBorn 26 Aug 1951.American mathematical physicist whose work in superstring theory made him the first physicist to be recognized with the Fields Medal in 1990, when he was 39 and at the Institute for Advanced Study in Princeton, New Jersey. The Fields Medal is regarded as having the status of a Nobel Prize for mathematicians. Witten was already known for his contributions in elementary particle theory, especially quantum field theory and string theory, and their mathematical implications, when in 1998 he received the Dannie Heineman Prize for Mathematical Physics. This award from the American Physical Society was given for “advances in elucidating the dynamics of strongly coupled supersymmetric field and string theories” in which he exploited “the deep physical and mathematical consequences of the electric-magnetic duality.”« |
MAGIC SQUARE: Calculate A-B-C
The aim is to place the some numbers from the list (11, 12, 17, 20, 21, 23, 26, 33, 41, 42, 47, 48) 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.
Find number abc
If c8368 - a91c1 = a9a1b find number abc. Multiple solutions may exist.
Which is a winning combination of digits?
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 619
NUMBERMANIA: Calculate the number 619 using numbers [5, 2, 3, 7, 45, 339] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once.
