The score of each student illustrates the use of mathematical operations.

Desmond's score before the last question is: 2
The subtraction equation to calculate his previous score is: [tex]3 - 1 = 2[/tex].

The given parameters are:

[tex]Correct = 5[/tex] --- score earned, when the answer is correct

[tex]Incorrect = -3[/tex] --- score earned, when the answer is incorrect

From the table (see attachment), Desmond's final score is:

[tex]Desmond = -1[/tex]

Because he answered the last question incorrectly, his previous score would be:

[tex]Previous = Desmond - Incorrect[/tex]

So, we have:

[tex]Previous = -1 - (-3)[/tex]

Remove brackets

[tex]Previous = -1 +3[/tex]

[tex]Previous = 2[/tex]

Hence, the subtraction equation to calculate his previous score is: [tex]3 - 1 = 2[/tex], and his previous score is 2
