If it is a variable-name, then just fetch the value of the variable.
To evaluate a variable expression, first substitute the values of the variables with their corresponding numerical values. Next, perform the arithmetic operations in the correct order, following the rules of parentheses, exponents, multiplication and division, and addition and subtraction (PEMDAS/BODMAS). Finally, simplify the expression to obtain the final value.
you have to deduce the variable and evaluate the expression.
evaluation, evaluate.
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.
You must substitute values for the variable.
A variable
If it is a variable-name, then just fetch the value of the variable.
To evaluate a variable expression, first substitute the values of the variables with their corresponding numerical values. Next, perform the arithmetic operations in the correct order, following the rules of parentheses, exponents, multiplication and division, and addition and subtraction (PEMDAS/BODMAS). Finally, simplify the expression to obtain the final value.
To evaluate a variable expression, replace all the variables with numbers and simplify the resulting numerical expression. 3m for m = 9 3(9)=27
you have to undo what ever's being done to the variable :p
you have to deduce the variable and evaluate the expression.
Take 3 and substitute into the expression given to you but not mentioned in the question here and evaluate the expression. "Sub and Solve" I say.
evaluation, evaluate.
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.
When you replace the variable with a number and perform the operations, you evaluate an expression. This process involves substituting the numerical value for the variable and simplifying the expression according to the given operations. Evaluation is a fundamental concept in mathematics and is used to determine the value of the expression under specific conditions.
The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.
