👉 Pertinence in a mathematical context refers to the statement or property that holds true for all values of the variables involved. For example, if we have an equation like x^2 + 3x - 4 = 0, this means that any value of x will result in a real number solution (i.e., it's always positive or negative). The term "pertinent" can be used to describe a mathematical statement that is true for all values of the variables involved.
