3//3 = 3/3/3 because in the process of multidivision, the number is divided by 3 consecutively. So 3/3/3 is the same as 3//3. 4//4 = 4/4/4/4 because it is divided by 4 consecutively, so it is the same as (0.25)^4. x//y=(x//(y-1))/x, while x//0=x because when y is equal to 0, the expression is undefined, so x//0 is set equal to x. (//) means multidivision because it is the process of dividing a number consecutively by the same number. (///) means powerdivision because it is the process of dividing a number by itself a certain number of times. (////) means tetradivision because it is the process of dividing a number by another number four times consecutively. Solve 10//10 with x//y=(x//(y-1))/x, while x//0=x: 10//10 = (10//9/)10 = 10^-8. Solve 10///10 with x///y=(x///(y-1))//x, while x///0=x: 10///10 = (10///9)//10. Solve 10////10 with x////y=(x////(y-1))///x, while x////0=x: 10////10 = (10////9)///10. Multidivision is the repeated division, powerdivision is the repeated multidivision, tetradivision is the repeated powerdivision.
