Expert Solution & Answer
Chapter 23, Problem 15RE
Explanation of Solution
Consider the following:
The below SQL statement that compute and finds the total cost of all line items in invoice number 11731:
/* Display the total cost of lineitem products */
SELECT SUM(Product.Price * LineItem.Quantity)
FROM Product, LineItem
WHERE LineItem.Invoice_Number = 11731
AND LineItem.Product_Code = Product.Product_Code
Explanation:
- The above “SELECT” statement that calculate and returns the “SUM(Product.Price * LineItem.Quantity)” columns from the “Product” and “LineItem” tables where “LineItem.Invoice_Number” is equal to “11731” and “LineItem.Product_Code” is equal to “Product.Product_Code”.
- “SUM(Product.Price * LineItem.Quantity)” – It finds and returns the total cost of all line items product value related to the given invoice number “11731”.
- “SUM” – It is a predefined function used to calculate the sum of a field.
- “Product...
- “SUM(Product.Price * LineItem.Quantity)” – It finds and returns the total cost of all line items product value related to the given invoice number “11731”.

1 An Extended Full Adder
In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj,
Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit
outputs: sj, Cout and rout.
The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA
ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only
on t₁ and to in the first place:
