MAGIC SQUARE: Calculate A-B+C
The aim is to place the some numbers from the list (7, 12, 17, 19, 24, 25, 29, 30, 35, 58) 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 48085 - bab64 = c0a2c 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.
Special golf ball
Two friends went out to play golf and were about to tee off, when one fellow noticed that his partner had just one golf ball.
“Don't you have at least one other golf ball?” he asked.
The other guy replied that no, he only needed the one.
“Are you sure?” the friend persisted. “What happens if you lose that ball?”
The other guy replied, “This is a very special golf ball. I won't lose it so I don't need another one.”
"Well,” the friend asked, “what happens if you miss your shot and the ball goes in the lake?”
“That's OK,” he replied, “this special golf ball floats. I'll be able to retrieve it.”
“Well what happens if you hit it into the trees and it gets lost among the bushes and shrubs?”
The other guy replied, “That's OK too. You see, this special golf ball has a homing beacon. I'll be able to get it back -- no problem.”
Exasperated, the friend asks, “OK. Let's say our game goes late, the sun goes down, and you hit your ball into a sand trap. What are you going to do then?”
“No problem,” says the other guy, “you see, this ball is florescent. I'll be able to see it in the dark.”
Finally satisfied that he needs only the one golf ball, the friend asks, “Hey, where did you get a golf ball like that anyway?”
The other guy replies, “I found it.”

Reginald Aldworth DalyDied 19 Sep 1957 at age 86 (born 19 May 1871). Canadian-American geologist who independently developed the theory of magmatic stoping, a process in which magma moves up through the Earth's crust the earth by shattering (but not melting) the overlying rock. Resulting broken blocks of denser rock sink, leaving space for the rise of the magma. This explained the structure of many igneous rock formations. Daly believed in the importance of field studies to investigate geologic processes. He based his theory of the origin of igneous rocks on an extensive study of hundreds of miles of landforms along the 49th parallel. From another project exploring the geology of the Samoan Islands, he developed theories relating glacial effects on sea level to the formation of coral atolls. His book Igneous Rocks and Their Origin (1914) was a popular instructional text for many years.« |
