Question

There are 9 players on a baseball team. After the game each player high-fives once with everyone else. How many high-fives were given?

Answer 1

32

Explanation:

Give each player a letter.

a, b, c, d, e, f, g, h, i

Each player high fives each other once.

a: b, c, d, e, f, g, h, i

b: c, d, e, f, g, h, i

c: d, e, f, g, h, i

d: e, f, g, h, i

f: g, h, i

g: h, i

h: i

Remember that you do not recount high-fives (as each player only gives it to another player once). Add the amount of high fives by counting.

32 is your answer.
