This is highly misleading, because a term, that cannot be reduced any further is called a value (See Call-By-Value). Since the input is already in normal Form, it should be the correct value. Using words like "compute" and "value" in a lambda calculus setting should be handled with much more care.

You can read the definition of Church numerals here: https://rosettacode.org/wiki/Church_numerals

The answer is 2, that is, this is the function that applies its first argument on its second argument 2 times:

λx.λy.x(xy) F v = F(F(v)) 

We can do calculations easily by the lambda calculator. In my opinion, everyone must give a try. It will worth your try for sure. Hostsailor We can do any type of calculation and it assures high accuracy and precise result.

the last question Evaluating Expressions #3, was changed to the more reasonable "what Church numeral does this expression correspond to", but this question still has the nonsensical "compute the integer value". The change should be made here as well.
