👉 In mathematical notation, "unsummable" is defined as an element that cannot be summed or added to. This means that the sum or addition of this element does not converge to a finite value. For example, in real analysis, if we have a function f(x) = x^2 + 3x - 2, then it's unsummable because its derivative is undefined at x=0 (since f(0)=0). However, if we consider the function f(x
