Boolean.
According to the Law of Absorption, A+(A*B) = A. Boolean B is "absorbed" by A.Similarly, A*(A+B) = A.
a ⊕ b = ab' + a'b
a+C+BD+B
For 2-input EX-OR gate, if one input is A, the other input is B, and the output is Y. Then the Boolean expression for EX-OR (XOR) function (gate) is Y=A⊕B The output Y is true if either input A or if input B is true, but not both.Y= ( (A and NOT B) or (NOT A and B) ) ;
In Electrical and Computer Engineering there is a particular kind of mathematics dealing with "logical expressions." This math is usually referred to as Boolean Algebra, the && represents the logical AND gate. This operator is used to compare two values (usually in binary algebra, which is Boolean Algebra on a base 2 number system, such as binary (the language of electronics and computers), a system with only 1 and 0 as possible values; or Boolean using true and false), an expression will be true only when both values are both true. i.e.: Will use Boolean for this system (only true or false are possible values). If we have an expression such as: y = a && b; whereas y, a, and b are variables which can equal only 0 (false) or 1 (true). You have these possible outcome combinations: | y | a | b | | 0 | 0 | 0 | | 0 | 0 | 1 | | 0 | 1 | 0 | | 0 | 1 | 1 |
The value of a + b depends on the values of the individual variables.The expression a + b cannot be simplified.
A - B = A + (-B) A - B = A + (-B) A - B = A + (-B) A - B = A + (-B)

There is no answer since there is no equation (nor an inequality), only an expression. Without the values of a and b, the expression cannot be evaluated.

An expression is anything that can be evaluated ("calculated"), to get a value. Numeric expressions are more common: anything that you can calculate, and get a number. For example, if a and b are numbers, a + b will give you another number - it is therefore a numeric expression. The variables by themselves are also numeric expressions.A boolean expression is anything that you can evaluate and get a result that is boolean, i.e., either true or false. Here are some examples:a == ba > ba >= 5 && a ba >= 5 && a ba >= 5 && a ba >= 5 && a
