WebMar 23, 2024 · In conventional algebra, letters and symbols are used to represent numbers and the operations associated with them: +, -, ×, ÷, etc. Doing so can help simplify and solve complex problems. In Logic, we seek to express statements, and the connections between them in algebraic symbols - again with the object of simplifying complicated ideas. WebExpress each of the following compound statements symbolically: The product x y = 0 if and only if either x = 0 or y = 0. The integer n = 4 if and only if 7 n − 5 = 23. A necessary condition for x = 2 is x 4 − x 2 − 12 = 0. A sufficient condition for x = 2 is x 4 − x 2 − 12 = 0.
