Find the value of the missing numbers; A = 1 B = 2 C = 0 D = 1 E = ? F = ?

Question

If
abcde=1 (where a,b,c,d and e are all positive real numbers)
then
what is the minimum value of a+b+c+d+e?

Answer 1

Thanks for the query.

The numbers are continuing with + 1, - 2. Like 1 + 1 = 2 and 2 - 2 = 0 and again 0 + 1 = 1.

So, the answer should be 1 - 2 = -1 and -1 + 1 = 0.
