Solve 8a-b(7+a) with a=50 and b=0: Algebraic Expression Evaluation

Question

What will be the result of this algebraic expression:

$8a-b(7+a)$

if we ascertain that:

$a=50,b=0$

00:00 Set up and solve

00:04 Let's substitute appropriate values according to the given data and solve

00:13 Let's calculate the multiplication

00:19 Always solve parentheses first

00:24 0 multiplied by any number always equals 0

00:29 And this is the solution to the question

Let's insert the given data into the expression:

8*50-0(7+50) =
400-0*57 =
400-0 =
400

$400$
