Explain how to find the sum negative sixty-five plus positive forty-one using a number line, then give the answer.
Move 65 places to the left of 0. Then move 41 places to the right.
41 - 65 = -24
Subtract the smaller number(41) from
the larger number(65) and use the sign of the larger number:
-65 + 41 = -24.
OR 41 + (-65) = -24.
To find the sum of negative sixty-five and positive forty-one using a number line, you can follow these steps:
1. Start by drawing a number line. Label the zero point in the middle and extend it in both directions.
2. Place a point on the number line to represent the starting point, which is negative sixty-five. Count sixty-five units to the left of zero and mark that point.
3. Now, you need to move right on the number line by positive forty-one. Count forty-one units to the right of the starting point and mark that point as well.
4. To find the sum, look at the point where you ended up after moving forty-one units to the right. Determine the value of that point on the number line.
Now, let's determine the answer:
Starting at negative sixty-five and moving forty-one units to the right brings you to negative twenty-four on the number line.
Therefore, the sum of negative sixty-five plus positive forty-one is equal to negative twenty-four.
