hello all ,
in this problem , we should Determine whether each sentence is a proposition
(we should Write T for true and F for each question, and if we are not sure explain)
(a) 2+3 = 7
(b) 2n + n is a prime for infinitely many n
(c) 2n = n2 for some n
(d) If the world is flat, then 2 + 2 = 4
(e) Your place or mine?
(f) Why is induction important?
(g) The difference of two primes
(h) A2 = 0 implies A = 0 for all A
(i) China is in Europe
so waiting yr help .
This is an easy, simple exercise.Quote:

If the answer is yes, this sentence is either true or false, then it is a proposition.
Otherwise, it is not a proposition.

Does it make any sense to ask if its true that two plus three equals seven?
If it does make sense to ask this, what is the answer?
Lets look at another:
(e) Your place or mine?
Does it make sense to ask if this is true or false?
