Before getting to the boolean exp, you must be clear on what an expression is, an expression is quite simply a combination of symbols(variables, numbers, etc). for example: 2, 2x, 2x-3, 2x+y, a/b,etc now any expression that has a value is called a mathematical expression, let us suppose 2x-y=3, here...

Now there are some expressions that have only two values, true or false. eg: 9>5 , the value is 'true'(nine is always greater than five) another example is 2 != 1 is true, because 2 is not equal to one. Such expression which can have only two values are called on boolean expressions. the values can only be true or false or in some representations 0 and 1. read less

A Boolean expression is a logical statement that is either TRUE or FALSE . Boolean expressions can compare data of any type as long as both parts of the expression have the same basic data type. You can test data to see if it is equal to, greater than, or less than other data.By these Boolean expressions...

An expression that produces either of the two value, true or false, as output. Example: answer to the question is a>b can produce only two outputs true or false. I hope it clears the concept.

An expression that results in a value of either TRUE or FALSE. For example, the expression 3 < 6 (3is less than 5) is a Boolean expression because the result is TRUE. All expressions that contain relational operators , such as the less than sign (<), are Boolean. The operators -- AND, OR, XOR, NOR,...
