No. To evaluate a variable, you simply take its value. When you assign a value to a variable, the evaluation of that operation is the value of the variable after assignment. There is no calculation required to evaluate a variable, unless that calculation is part of the right-hand operand of an assignment operation, in which case the calculation is evaluated first and the result of that evaluation (the value) is then assigned to the variable which is then evaluated.

Evaluate the expression 12?
Constant values are expressions as well, still I don't think they are so hard to evaluate... well, in this case it is twelve
How many values can a boolean variable have?
Two, True or False.
When do you declare a variable method and a class final?
When There is No Need to Change the Values of the Variables In Entire lifetime of That variables then we must use that Variable as Final Variable.
What is the difference between an array shift and unsetting a variable in PHP?
By shifting the values in an array, you are moving a key's value to the previous key. The very first key's value is obliterated. By shifting all values in the array, all keys will have a value of NULL. Unsetting a variable is entirely different -- performing a variable unsetting causes the variable to have a value of NULL, as if it was never set.
What data or variable type is used for variables that will only have the values true or false?
Boolean
To evaluate a variable expression you must do what to values for the variable?
You must substitute values for the variable.
How do you evaluate a expression?
Replace all the variables in the expression by their numerical values and calculate the result.
Finding values of polynomial functions?
Substitute that value of the variable and evaluate the polynomial.

What does evaluate mean in mtah?
It means to replace the variable or variables with actual values, and do the calculations.
How do you evaluate equations?
To evaluate means to find the value. Substitute the values of the variables and calculate the value. [You may need to solve for the values of the variables first.]
How does a variable affect the result of an experiment?
Modifying the values of a variable the results of the experiments are modified.
What is necessary to evaluate chi-square?
It is necessary to have a null hypothesis. This must be used to calculate expected values of the variable under study for various categories. These must be at least 5: if not, you need to combine categories. You also need the observed values. Finally, you need to know the degrees of freedom for the chi-square variable.
To evaluate a function for a specific value substitute the value in for what?
You substitute the variable for its value. Or you substitute the variables for each of the values.
How do you evaluate an expression when given values for the variables?
You replace each variable by its value. Then you do the indicated calculations.
How do you evaluate algebraic expressions?
Replace the variables with the correct values and calculate using the order of operations
What is the definition of equivalen variable expressions?
Two expressions are "equivalent" if they have the same result for any values of the variable or variables.
