Calculate the number 1161
NUMBERMANIA: Calculate the number 1161 using numbers [9, 1, 8, 1, 66, 643] 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 (2, 4, 6, 8, 10, 12, 17, 33, 35, 37) 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 481a1 + 6cab1 = 1c8b22 find number abc. Multiple solutions may exist. 
Growing Tomatoes
A beautiful woman loved growing tomatoes, but couldn't seem to get her tomatoes to turn red. One day, while taking a stroll, she came upon a gentleman neighbor who had the most beautiful garden full of huge red tomatoes.
The woman asked the gentlemen,"What do you do to get your tomatoes so red?" The gentlemen responded, "Well, twice a day I stand in front of my tomato garden naked in my trench coat and flash them. My tomatoes turn red from blushing so much."
Well, the woman was so impressed; she decided to try doing the same thing to her tomato garden to see if it would work. So twice a day for two weeks she flashed her garden hoping for the best.
One day the gentleman was passing by and asked the woman, "By the way, how did you make out? Did your tomatoes turn red?"
No", she replied, "but my cucumbers are enormous."
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. Charles Proteus SteinmetzBorn 9 Apr 1865; died 26 Oct 1923 at age 58. German-American electrical engineer and inventor whose theories and mathematical analysis of alternating current systems helped establish them as the preferred form of electrical energy in the United States, and throughout the world. In 1893, Steinmetz joined the newly organized General Electric Company where he was an engineer then consultant until his death. His early research on hysteresis (loss of power due to magnetic resistance) led him to study alternating current, which could eliminate hysteresis loss in motors. He did extensive new work on the theory of a.c. for electrical engineers to use. His last research was on lightning, and its threat to the new AC power lines. He was responsible for the expansion of the electric power industry in the U.S. |
