One

A multiplicative identity of a semiring. For a semiring R, 1 is defined as an element so that for every a being an element of R:
1⊗a = a⊗1 = a

Min-tropical semiring is a semiring (ℝ ∪ {+∞}, ⊕, ⊗) with ⊕ defined as min, and ⊗ defined as the addition of two numbers. By that definition, zero is +∞, and one is 0
