I’m a bit confused about the description of this challenge. It says

Return the sum of those two numbers plus the sum of all the numbers between them.

the “return the sum of those two numbers” part mean what? When I see the test case result, it is just the sum of all the numbers between the two numbers provided.

So, what does “return the sum of those two numbers” actually mean?

Ohh, I seee. At first, I thought it was (1+5)+(1+2+3+4+5), because the example says “sum all numbers between them (1 and 5) both INCLUSIVE”. So I’m really stuck on the word “inclusive” and assuming like that.

My english is not good enough yet, sometimes I’m experiencing misinterpretation like this.
