Use summation notation to express each of the following calculations:

a. Add 1 point to each score, then add the resulting
values.
b. Add 1 point to each score and square the result,
then add the squared values.
c. Add the scores and square the sum, then subtract
3 points from the squared value.

a. The summation notation for adding 1 point to each score and then adding the resulting values can be expressed as:

Σ(score + 1)

b. The summation notation for adding 1 point to each score, squaring the result, and then adding the squared values can be expressed as:
Σ((score + 1)^2)

c. The summation notation for adding the scores, squaring the sum, and then subtracting 3 points from the squared value can be expressed as:
(Σscore)^2 - 3

a. To express the calculation of adding 1 point to each score and then adding the resulting values using summation notation, we can use the Greek letter sigma (Σ). Assuming we have n scores, the expression would be:

Σ(x_i + 1)

In this notation, x_i represents each individual score, and the Σ symbol denotes the summation. The index i ranges from 1 to n, indicating that we consider each score in the summation.

b. For the calculation of adding 1 point to each score, squaring the result, and then adding the squared values, we can use the following summation notation:

Σ((x_i + 1)^2)

Similarly, x_i represents each individual score, the Σ symbol denotes the summation, and the index i ranges from 1 to n to include each score.

c. Lastly, for the calculation of adding the scores, squaring the sum, and then subtracting 3 points from the squared value, the summation notation would be:

(Σx_i)^2 - 3

In this case, the expression within the parenthesis Σx_i represents the summation of all the scores, and then we square that value. Finally, we subtract 3 from the squared sum. Again, the index i ranges from 1 to n, covering each score.
