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

On This Day

First stainless steel cast In 1913, the first true stainless steel was cast in Sheffield, England. It was a steel alloy that contained 0.24% carbon and 12.8% chromium. English metallurgist, Harry Brearley was developing a more erosion-resistant steel for rifle barrels. In order to examine the grain structure of the steel he needed to etch samples with acid before examining them under the microscope. The etching reagents he used were based on nitric acid, and he found that this new steel strongly resisted chemical attack. He then exposed samples to vinegar and other food acids such as lemon juice and found the same result. Brearley realized that this new steel could also revolutionise the cutlery industry.
