− | It's often necessary to express things in the form <math>\text{If } A\text{ then }B</math>. In that form, <math>A \rightarrow B</math> is called a '''conditional''', <math>A</math> is the antecedent, and <math>B</math> is the '''consequent'''. In order for the expression to hold, when <math>A</math> is true, <math>B</math> must also be true. However, conversely, when <math>A</math> is false, the statement is trivially true regardless of <math>B</math>. | + | It's often necessary to express things in the form <math>\text{If} A\text{then}B</math>.
