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!

On This Day

Mikhail Semyonovich Tswett Born 14 May 1872; died 26 Jun 1919 at age 47.Russian botanist, the “father of chromatography,” who developed and named the adsorption chromatography technique of separating plant pigments by extracting them from leaves with ether and alcohol and percolating the solution through a column of calcium carbonate. The components of the mixture moved at different rates, producing a series of bands. He is known in particular for his study of the chlorophylls and the carotenoids. However, in Tswett's own lifetime, chromatography remained virtually unrecognized as a scientific tool. In the 1930s, it was rediscovered and then spread worldwide. The chromatography technique he invented is now widely used to separate substances from mixtures. (Also spelled Tsvet.)
