Topic: School problem, 3 a class
Helped the child to do mathematics. Such problems (by the own words): 1. At school all caught chess and arranged chess tournament. In it give 3 points for a victory, 1 point for a drawn game and 0 for loss. Masha bragged that for 38 played batches it typed 80 points. Masha lost what maximum quantity of batches? 2. It is possible to present number 14 the total 6 odd numbers. The order of numbers thus does not play a role. How many different variants/combinations exist for this purpose? And here I think that except as search it not to solve. Or to solve?
