Answer:
Click the AutoSum button on the Standard toolbar, then press ENTER
Explanation:
Excel offers a range of options to perform various mathematical operations. When numeric values are being inputted into cells, either columns or rows, the AutoSum function which is located in the home Taskbar allows for a very fast addition of the total values in the column or rows. Once the cell after the last cell value is selected, the AutoSum function is selected and the ENTER button is pressed, this will use the sum function of excel to quickly provide the total sum of all the values in the column.

Answer:
Yes. Pseudocode is an improvement over the IPO chart because it lays out the sequence of steps for a particular program
Explanation:
The input–process–output (IPO) chart is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process. The chart has three components (Input, Process and Output), and you write the description of each component in plain English, not code or mathematical formulas.
Pseudocode is a procedure for solving a problem in terms of the actions to be executed and the order in which those actions are to be executed.
Pseudocode is an improvement over the IPO chart because it shows the step by step sequence to be followed by a particular program unlike the IPO chart which just break the program into Input, Process and Output.
