Problem 2 Solution
2.076923077
The key idea:
The order of operations may need to be emphasized again, especially the proper
use of parentheses to evaluate the denominator correctly.
Solution Steps for Problem 2:
Answer:
 Recall the order of operations is Parentheses, Exponentiation, Multiplication or Division, Addition or Subtraction.
 One "tricky" part was covered in "Working with Numbers:"
1^2 is evaluated as 1, since the exponentiation is done before the negation.
 Another step that you might miss is putting the denominator inside parentheses, since 3^2 is divided by the WHOLE denominator.
 Entering the following key strokes in a T182 style calculator produces the answer:
3 ^ 2 / ( 1 + ( 22 / 3 + 4 * (  (1 ^ 2) ) ) ) ENTER
