Please explain this and answer in a mathematical way, rather than computer science way.

Part 1. Problem Solving p. 96 ex. 11 (Algorithm Workbench)- 5 points If the following pseudocode were in an actual program, what would it display? Declare Integer a = 5 Declare Integer b = 2 Declare Integer c = 3 Declare Integer result Set result = a + b c p. 76 ex. 3, 4, 6 (Debugging Ex.) - 15 points 3. The following code will not display the results expected by the programmer. Can you find the error? Declare Real lowest, highest, average Display "Enter the lowest score." Input lowest Display "Enter the highest score." Input highest Set average = lowest + highest / 2 Display "The average is", average, "." 4. Find the error in the following pseudocode Display "Enter the length of the room." Input length Declare Integer length 6. Find the error in the following pseudocode Declare real pi Set 3.141 59265 = pi Display "The value of pi is = ", pi
