1824982	I have a question about lambda calculus. I just read that it doesn't matter in which way expressions get evaluated. So my question is: $(\lambda f.\lambda x.f(fx)) (\lambda y.y+1) 2$ so we can evaluate this expression like this: $(\lambda f.\lambda x.f(fx)) (\lambda y.y+1) 2$ $(\lambda x.(λy.y+1)(\lambda y.y+1)x) 2$ $((\lambda y.y+1)(\lambda y.y+1)2)$ $(\lambda y.y+1)(2+1)$ $2+1+1$ but what if we start evaluation like this: $(\lambda f.\lambda x.f(fx)) (\lambda y.y+1) 2$ $(\lambda f.\lambda x.f(fx)) (2+1)$ ??? So how can I continue evaluation now? I know there should be some rules not letting me to start evaluation like this but what is that?	4	Integer	Computer Science	University	2

530162	Nagoya Amusements Corporation places electronic games and other amusement devices in supermarkets and similar outlets throughout Japan. Nagoya Amusements is investigating the purchase of a new electronic game called Mystic Invaders. The manufacturer will sell 20 games to Nagoya Amusements for a total price of 176,000 Yen. Nagoya Amusements has determined the following additional information about the game: a. The game would have a 5-year useful life and negligible salvage value. The company uses straight-line depreciation. b. The game would replace other games that are unpopular and generating little revenue. These other games would be sold for a total of 28,000 Yen. c. Nagoya Amusements estimates that Mystic Invaders would generate annual incremental revenues o 204,000 Yen (total for all 20 games). Annual incremental out-of-pocket cost would be (in total): maintenance, 42,000 Yen; and insurance, 8,500 Yen. In addition, Nagoya Amusements would have to pay a commission of 48% of total revenues to the supermarkets and other outlets in which the games were place. (Ignore income taxes.) Required: 1.

So how can I continue evaluation now? I know there should be some rules not letting me to start evaluation like this but what is that?

Nagoya Amusements Corporation places electronic games and other amusement devices in supermarkets and similar outlets throughout Japan. Nagoya Amusements is investigating the purchase of a new electronic game called Mystic Invaders. The manufacturer will sell 20 games to Nagoya Amusements for a total price of 176,000 Yen. Nagoya Amusements has determined the following additional information about the game: a. The game would have a 5-year useful life and negligible salvage value. The company uses straight-line depreciation. b. The game would replace other games that are unpopular and generating little revenue. These other games would be sold for a total of 28,000 Yen. c. Nagoya Amusements estimates that Mystic Invaders would generate annual incremental revenues o 204,000 Yen (total for all 20 games). Annual incremental out-of-pocket cost would be (in total): maintenance, 42,000 Yen; and insurance, 8,500 Yen.

If the United States imposes a trade restriction on Japan (i.e. a tariff or a quota), this could lead to a reduction in United States exports to Japan because fewer imports from Japan would result in U.S. Dollar appreciation relative to the Japanese Yen. II. If the United States imposes a trade restriction on Japan (i.e. a tariff or a quota), this could lead to a reduction in United States exports to Japan because fewer imports from Japan would reduce income in Japan, reducing demand for goods and services produced in the United States by Japanese households and businesses.
