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!
Example of the correct math expression:

A police officer pulls over th...
A police officer pulls over this guy who's been weaving in and out of the lanes. He goes up to the guy's window and says, "Sir, I need you to blow into this breathalyzer tube."
The man says, "Sorry, officer, I can't do that. I am an asthmatic. If I do that, I'll have a really bad asthma attack."
"Okay, fine. I need you to come down to the station to give a blood sample."
I can't do that either. I am a hemophiliac. If I do that, I'll bleed to death."
"Well, then, we need a urine sample."
"I'm sorry, officer, I can't do that either. I am also a diabetic. If I do that, I'll get really low blood sugar."
"All right, then I need you to come out here and walk this white line."
"I can't do that, officer."
"Why not?"
"Because I'm drunk."

On This Day
Jeremias B. RichterDied 4 Apr 1807 at age 45 (born 10 Mar 1762).Jeremias Benjamin Richter was a German chemist who discovered the law of equivalent proportions. He studied chemistry in his spare time while in the Prussian army (1778-1785) and afterwards while earning a Ph.D. in mathematics (1789). Richter was much influenced by Immanuel Kant, whose lectures he may have attended, in the contention that science is applied mathematics. Richter looked for mathematical relationships in chemisty, convinced that substances reacted with each other in fixed proportions. He showed such a relationship when acids and bases neutralize to produce salts (1791). Thus he was the first to establish stoichiometry, which became the basis of quantitative chemical analysis. He died of tuberculosis at age 45 years. |
