Implies
(Built-in Mathematica Symbol) Implies[p, q] represents the logical implication p \[DoubleRightArrow] q.
Mathematica represents Boolean expressions in symbolic form, so they can not only be evaluated, but also be symbolically manipulated and transformed. Incorporating ...
Mathematica treats equations as logical statements. If you type in an equation like x^2+3x==2, Mathematica interprets this as a logical statement which asserts that x^2+3x is ...
