Calculate the number 1076
NUMBERMANIA: Calculate the number 1076 using numbers [2, 6, 4, 8, 30, 426] 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 (8, 11, 18, 23, 26, 33, 36, 39, 45, 46, 68, 86) 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 2a4bb - 1b7a3 = 106ac find number abc. Multiple solutions may exist.
Special Delivery
It was mailman George's last day on the job after 35 years of delivering the mail through all kinds of weather. When he arrived at the first house on his route, the whole family came out, roundly congratulated him, and sent him on his way with a tidy gift envelope.
At the second house they presented him with a box of fine cigars. The folks at the third house handed him a selection of terrific fishing lures.
At the next house, he was met at the door by a strikingly beautiful woman in a revealing negligee. She took him by the hand, and led him up the stairs to the bedroom where she blew his mind with the most passionate love he had ever experienced.
When he'd had enough, they went downstairs, where she fixed him a giant breakfast: eggs, potatoes, ham, sausage, blueberry waffles and fresh-squeezed orange juice. When he was truly satisfied, she poured him a cup of steaming coffee. As she was pouring, he noticed a dollar bill sticking out from under the cup's bottom edge.
"All this is just too wonderful for words," he said, "but what's the dollar for?"
"Well," she said, "last night, I told my husband that today would be your last day, and that I wanted to do something special for you. I asked him what to give you. He said, 'Screw him. Give him a dollar.'"
"Breakfast was my idea."
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.
Ferdinand von LindemannBorn 12 Apr 1852; died 6 Mar 1939 at age 86.Carl Louis Ferdinand von Lindemann was a German mathematician who was the first to prove that is transcendental (it is not a solution of any algebraic equation with rational coefficients). This finally established the insoluble nature of the classical Greek mathematical problem of squaring the circle (constructing a square with the same area as a given circle using ruler and compasses alone.) In 1873, Lindemann visited Hermite in Paris and discussed the methods which Hermite had used in his proof that e, the base of natural logarithms, is transcendental. Following this visit, Lindemann was able to extend Hermite's results to show that was also transcendental (1882).«[DSB and other sources give death date as 6 Mar 1939. EB gives 1 Mar 1939.] |
