(863) 409-3952 Can squeal with glee on twitter. 1 Boolean Algebra Operations ¶ There are only two values, $$\binary{0}$$ and $$\binary{1}\text{,}$$ unlike elementary algebra that deals with an infinity of values, the real numbers. Since there are only two values, a truth table is a very useful tool for working with Boolean algebra. A+ C+ AB d. The basic logical operations are AND, OR and NOT, which are symbolically represented by dot, plus sign, and by over bar / single apostrophe. The boolean algebra calculator uses the basic laws like identity law. Partial Fractions. The secondary operators are exclusive or (often called xor) and exclusive nor (sometimes called equivalence).
