+[explain] Explain why the sky is blue in two sentences.
+-> Sunlight contains all colors mixed together. When it enters the atmosphere, it hits tiny gas molecules and collisions cause the light to scatter in all directions — that scattered light we see as blue.
+
+Example: look at the sky at sunset. Light passes through more air and passes more times through the different gases. The gas molecules scatter shorter wavelengths (blue) far more than longer ones, so the blue light gets scattered away before it reaches your eyes.
+
+So the sky looks blue because it

+[maths_on (thinking on)] A shop sells pens at 12 rupees each. How much do 7 pens cost?
+-> <|channel>thought
+The question asks how much 7 pens cost. The price per pen is 12 rupees.
+The number of pens is 7.
+Cost = price × number of pens.
+Cost = 12 × 7.
+12 × 7 = 84.
+Check: 7 × 12 = 84, and 84 ÷ 7 = 12.

+[logic_on (thinking on)] If all bloops are razzies and all razzies are lazzies, are all bloops lazzies?
+-> <|channel>thought
+The user is asking a playful logic puzzle: if all bloops are razzies, then all bloops are lazzies. The key is to define the logical relationship carefully. Let me parse the statement: "every bloop is razzies" — this is a universal statement, so it certainly holds for every bloop. Then "all razzies are lazzies" — this is a statement about the subset of razzies. The conjunction "and" is needed. So the logical structure is: if all bloops are razzies, then all bloops are lazzies.
