Assuming that everyone kisses everyone else only one time each, the first person has to kiss all 99 others. The second one only has to kiss the remaining 98, the third the remaning 97 and so on, so you'd have to add 99+98+97+96+95... etc.
You can add the opposing numbers up to 100 each (99+1, 98+2, 97+3, 96+4) and count how many 100 result.
The final number of kisses would then be 4950.

There are 3 people at a party If each person must shake hands with every other person at the party exactly once how many handshakes will there be?
With 3 people, there are only 3 handshakes: AB, AC, and BC. Where it gets interesting is at a party with, say, 10 people ... 45 handshakes. Or in the US Senate when all 100 Senators are present ... 4,950 handshakes.
If there are 8 people at a party and every person shakes hands with everyone else at the party how many handshakes will there be?
There will be 28 handshakes. If you ask each person how many handshakes they had they will tell you 7 making 7 x 8 = 56 handshakes in all. But every hand involves two people, so every handshake has been counted twice, thus there are 56 / 2 = 28 handshakes in all.
I count 24 heads and 80 legs. How many pigs and how many chickens are out there?
Heads: P + C = 24C = 24 - PLegs: 4P + 2C = 80Substitute, from heads: 4P + 2 (24 - P) = 804P + 48 - 2P = 802P = 32P = 16C = 24-P = 8====================Check:P + C = 16 + 8 = 244P + 2C = 4(16) + 2(8) = 64 + 16 = 80 yay!
15 friends at a party and all kisses each other then how many kisses?
This is a variation on the handshake problem which say if there are n people at a party and every one shakes hands with every other one, how many handshakes are there? It is well know that kisses in fact are cleaner than handshakes which to tend to pass diseases. So thanks for a cleaner version of this classic math problem! n(n-1)/2 is the formula for the number of handshakes OR kisses for n people at a party. If you case, 15x14/2 which is 15x7 or 105.
