The process of finding a value for a variable that results in a true sentence is called . A + B = 5 the expression can be true or false that depend on the value of A and B if the value of A=2 and B=3 then the given expression is true and comes under True number sentence but if the value of A=4 and B=2 then the given expression is false number sentence. We write 14 + x instead of 14 + . The reason the sentence “\(3 + x = 12\)” is not a statement is that it contains a variable. No prime number is even. Definition: A closed sentence is an objective statement which is either true or false. Example: Create a sentence that includes numbers 3 and 4 along with the words “more” and “and”. Conditional Statements. These include sentences like: x + 5, a - 2b + 3c = d, 2x + 3y 6, etc. The lesson then introduces students to sentences that are neither true nor false but are algebraic equations, also called open sentences, such as x + 3 = 7 or 2 x= 12. 3 + 2 = 2. In mathematical logic, an open sentence is a sentence which contains variables. For example, an equation such as \(x^2 -5 = 0\) is not a statement. An open sentence is neither true nor false until the variables have been replaced by specific values. Truth Value of Open Sentences Sometimes it is difficult to determine the truth value of a sentence. Depending on what \(x\) is, the sentence is either true or false, but right now it is neither. This article is a technical mathematical article in the area of predicate logic. Mathematical statements. Algebraic Sentences We know that algebraic sentences give the relation between two algebraic expressions.
