In a small town, there is only one barbershop. Not all men in town go to the barber shop. Thus, the city's male population can be divided into two groups: those who shave alone and those who go to the barber. So we assume the barber shaves all men who don't shave themselves, right?
It is interesting to think of the points on the Euclidean line (the line of geometry you knew in elementary school) as numbers. This invention was responsible for a great revolution in seventeenth-century mathematics. It is the famous Cartesian coordinate idea. With it we can think of geometric problems using numbers and thus algebra.
Possible values for x? We can write the expression as follows: This number is integer if and only if x + 19 is a divisor of 80. Since 80 has 10 integer divisors, then there are 10 possible values for x. Back to statement Challenge 27 What is the division quotient?
