What does it you to evaluate an algebraic expression?
To evaluate an algebraic expression means to simplify the expression as much as possible by replacing the variables in an expression with the numerical values given to you.Ex:Example of Evaluating an Algebraic ExpressionTo evaluate the algebraic expression '4.5 + x' for x = 3.2, we need to replace x with 3.2 and then add. 4.5 + x = 4.5 + 3.2=7.7Solved Example on Evaluating an Algebraic ExpressionEvaluate the algebraic expression p + 3q + 2p - 3q, for p = 2 and q = - 5.Choices:A. 12B. 18C. 3D. 6Correct Answer: DSolution:Step 1: p + 3q + 2p - 3q [Original expression.]Step 2: = (p + 2p) + (3q - 3q) [Group the like terms together.]Step 3: = 3p [Solve within the grouping symbols.]Step 4: = 3 x 2 [Substitute 2 for p.]Step 5: = 6 [Multiply.]

How do you evaluate expression 43 plus 68 plus 57 and justify with each step?
do 43+57 which is 100 then do 100+68 which is 168 the answer is 168
How do you evaluate 6-7 plus 5?
There are two steps to the process: Step-1: Subtract 7 from 6. The answer to this step is -1. Remember that as you proceed to the next step. Now, go on to the next step. Step-2: Take the -1 from the first step, and add 5 to it. The new result is then +4 . The +4 that you have now is the value of the entire original expression.
How do you work out sums?
Step by step and following the mathematical instructions as given by the expression.
