there are , in a certain league , 10 teams , and each team face another team for a total of 10 times . how many games are played in the season ?
"by using the formula , t [ n ( n - 1 ) / 2 ] , where t = no . of games between two teams and n = total no . of teams , we get : 450 option a ."
multiply(multiply(subtract(10, const_1), 10), divide(10, const_2))
