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

William Smith Died 28 Aug 1839 at age 70 (born 23 Mar 1769). English geologist and engineer who extended the science of stratigraphy. His early work was as a miner and an engineer, for a canal-digging company. From this experience he observed the difference in rock layers. He also recognized that the same succession of fossil groups from older to younger rocks could be found in many parts of England, which he called the principle of faunal succession. He travelled the entire country to verify that relationships between the strata and their characteristics were consistent everywhere. Thus Smith created a profile of the entire country of England. His great geologic map of England and Wales (1815) set the standard for modern geologic maps. Many of the colourful names he gave to the strata are still in use today.«[Image: portrait of William Smith by Abner Lowe in the 1920s]
