Textbook Problem

Use summation notation to express each of the following calculations:

**a.**Add 1 point to each score, and 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.**

To determine

The summation notation to add 1 point to each score and then add the resulting values.

Explanation

**Calculation:**

Let *X* represents the scores.

Then addition of 1 point in each score is represented by

Let, *Y* represents the square of sum of all scores in summation notation, then

**b.**

To determine

The summation notation to add 1 point to each score, square the result and then add the squared values.

**c.**

To determine

The summation notation to add the scores, square the sum and then subtract 3 points from the squared value.
