You're in caves, year 386 and the score is 150-150 and you have 5 red and 3 green crystals in your backpack. All of your teammates are in blue cave, the question is: how many blue crystals should each teammate drop to finish the battlefield?

Using only addition, how do you add eight 8’s and get the number 1000 :music:

Ungoliant got it correct, but it should be a human answering the question. So, i guess I win? I don't know. It's 8 blue crystals per teammate.

888 + 88 + 8 + 8 + 8 = 1000.

I posted early, so I'm changing the question to avoid creating an unfair situation.

Imagine an Eagle named White sitting on his nest located on the roof of a train station. White is a very ambitious eagle, he claims he is the fastest bird to have ever existed, and to prove that he used to race trains on his free time.

But racing trains is simple! Now, he has a better challenge. He starts flying from his nest to a train that is moving toward the station, turns back just as he reaches the train's point closest to station, and starts flying back toward the station. After he reaches the station, he turns back once more and flies toward the train, then repeats the same procedure until the train reaches the station.

Ignore the length of White and assume he changes speed while turning back instantly.

So, if White starts flying with a velocity of 80km/h towards the train when the trains is exactly 100km away from the station, and the train has a velocity of 50km/h, how much distance will White fly in total?

No right answers in 30 minutes, so I explain the solution.

So you can do some direct maths and try to solve an infinite series...

Or you can see that the train with 50km/h speed will travel the 100km road in 2 hours, and that is exactly the amount of time White will fly with a speed of 80km/h. 80km'h * 2h = 160km. (:

Which 3 numbers give same result when multiplied or added?

so x+y+z = x*y*z

so x+y+z = x*y*z
There's also some general solutions to that.

I'm not sure whether these are all, but they work for sure:

1. x= -y and z=0. x+y+z = 0 = x*y*z

2. x=y=z=0.

There is a number, when you add it to its square and the digits of that summation added together bring it back to itself. What is this number?

Ok just a little hint: x*x+x=yz and y+z=x

(please note: yz is NOT y*z it's a two digit number like 95)
