Clara played a video game before she left the house to go on a walk. She started with 0 points, lost 6 points 3 times, won 4 points, and then lost 2 points. How many points did she have when she left the house to go on a walk? Write and evaluate an expression to represent Clara’s points.
come on ... 0 - 6*3 + 4 - 2 = ___
To represent Clara's points, we can start with 0 and subtract the points she lost three times (6 points each time), and then add the points she won (4 points), and finally subtract the points she lost again (2 points).
The expression would be:
Points = 0 - 6 * 3 + 4 - 2
Evaluating this expression:
Points = 0 - 18 + 4 - 2
Points = -14
Therefore, Clara had -14 points when she left the house to go on a walk.
To find out how many points Clara had when she left the house, we need to follow the given sequence of events and perform the calculations step by step.
1. Clara started with 0 points.
2. She lost 6 points three times. This means she lost 6 points * 3 = 18 points in total.
3. After losing 18 points, Clara's score decreased from 0 to -18.
4. Next, she won 4 points. Adding 4 points to her current score of -18, Clara's score increased to -14.
5. Finally, she lost 2 points. Subtracting 2 points from Clara's current score of -14, her score decreased to -16.
Therefore, Clara had -16 points when she left the house to go on a walk.
To express Clara's points using an expression, we can use the following formula:
0 - (6 * 3) + 4 - 2
Now, let's calculate the expression:
0 - (6 * 3) + 4 - 2 = 0 - 18 + 4 - 2 = -16
So, Clara had -16 points when she left the house.
