Question

the table shows alejandros golf scores (relative to par) over a 4 - round tournament.
round score (strokes)
1 +2
2 -4
3 -2
4 +3
what is alejandros cumulative score for the tournament?

Explanation:

Step1: Define the scores

Let the scores of each round be \(a_1 = + 2\), \(a_2=-4\), \(a_3 = - 2\), \(a_4=+3\).

Step2: Calculate the cumulative score

The cumulative score \(S=a_1 + a_2+a_3 + a_4\). Substitute the values: \(S=(+2)+(-4)+(-2)+(+3)\). First, \(2+( - 4)=2 - 4=-2\). Then, \(-2+( - 2)=-2-2 = - 4\). Finally, \(-4+(+3)=-4 + 3=-1\).

Answer:

\(-1\)
