2^5 + 2^4 - 2^2
(the 2^2 are the number of strings that look like this: 00**111)
Infinitely many if the numbers are not restricted to being integers.
x1 x2 x3 are not negative numbers.
we have: x1 + x2 + x3 = 11
How many solutions would there be for the equation?
ok so im thinking each x can have numbers 0 -11.
so 11 * 11 * 11 different solutions.
