A logical test is any value or expression that can be evaluated as being true or false.

to find the value of an expression, you need to
You evaluate the expression !! :)
The value of the expression 4.23 is simply 4.23 itself. In mathematics, an expression typically consists of numbers, symbols, and operators, but in this case, the expression is already a numerical value. Therefore, the value of the expression 4.23 is 4.23.
To find the value of an algebraic expression is to evaluate it.
Logical Test
The conditional operator in C (and C++, C# and other languages) consists of two symbols, '?' and ':'. Together, they can be used to form an expression from three subexpressions:e1 ? e2 : e3The conditional operator is evaluated in two steps; first, the expression e1 is evaluated, if it has a true value, then e2 is evaluated and its value is returned as the result of the entire expression, otherwise (if e1 is false) e3 is evaluated and its value is returned as the result of the entire expression.
In C, any non-zero expression is true and any zero expression is false.
It is 6a + 12, an expression which cannot be evaluated without the value of a.
The expression cannot be evaluated without knowing the value of m.
It is the expression -2m + 92. This cannot be evaluated without knowing the value of m.
8 + x 40 is not a valid mathematical expression.
It is simply S-53: the expression cannot be simplified. And since the value of S is not known it cannot be evaluated.
It is simply x - 6. The expression cannot be evaluated because the value of x is not given.
18
It is x + 6. The expression cannot be evaluated without knowing the value of x.
It is n + 14920, an expression which cannot be simplified; nor can it be evaluated without the value of n.
