Rules
Guess the NERDLE in 6 tries. After each try, the color of the tiles will change to show how close your guess is to the solution.
If the tile becomes GREEN, your number or operation is located at correct place. If the tile becomes RED, your number or opeartion exists within the expression, but at different place.
- Each try is a calculation (math expression).
- You can use 0 1 2 3 4 5 6 7 8 9 + - * / or =.
- It must contain one “=”.
- It must only have a number to the right of the “=”, not another calculation.
- Standard order of operations applies, so calculate * and / before + and - eg. 3+2*5=13 not 25!
Joke Of The Day
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.”
On This Day
FluorineIn 1886, Henri Moissan's discovery of fluorine gas was announced at the Paris Academy of Science, two days after his first successful experiment to isolate the element, which he tested with silicon to find it burst into flame. “One can indeed make various hypotheses on the nature of the liberated gas; the simplest would be that we are in the presence of fluorine, but it would be possible, of course, that it might be a perfluoride of hydrogen, or even a mixture of hydrofluoric acid and ozone sufficiently active to explain such vigorous action as this gas exerts on crystalline silicon.” This conservative announcement was read to the Academy by Debray, for Moissan was not then a member. The president appointed a committee to check the discovery.* |
