the variable represents any number that the P could be
There could be a variable in the numerator which is not defined. For example, [tan(x)]/3 has no variable in the denominator but the expression is not defined for x = pi/2, for example (90 deg).
n - 8 is the expression for the difference of eight and a number.'Number' is a variable, so the variable must be a letter (in this case, 'n'). 'The difference' is going to be the subtraction symbol that is in between the 'number' and eight, so it must be n - 8. It could, of course, be 8 - n.
In mathematics, the symbol "X" typically represents an unknown variable. Therefore, "XX1X" could be interpreted as a mathematical expression with variables. Without further context or specific instructions, it is difficult to determine a precise meaning for this sequence of symbols. It is possible that it could represent a polynomial, an algebraic expression, or a placeholder for a specific value in a mathematical equation.
With no context it is difficult to be sure but I suggest that n is a counter: a variable that goes 1, 2, 3, 4, ...and x, unfortunately, represents multiplication. I say unfortunately because the accepted symbol nowadays is * rather than x.So the expression is to multiply a number by its predecessor. The expression could represent the number of permutations of two objects selected from n distinct objects.
