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

Vilfredo Pareto Born 15 Jul 1848; died 20 Aug 1923 at age 75. Italian economist and sociologist, known for his application of mathematics to economic analysis and for his theory of the 'circulation of elites'. His initial five-year course in civil engineering, graduating in 1870, gave him a grounding in mathematics. While working as an engineer, he studied philosophy and politics and wrote many periodical articles in which he was one of the first to analyse economic problems with mathematical tools. Pareto's first work, Cours d'economie politique (1896-97), included his famous 'law' of income distribution, a complicated mathematical formulation attempting to prove the distribution of incomes and wealth in society is not random and that a consistent pattern appears throughout history, in all parts of the world and in all societies.
