double check
Apologies for the mistake. A negative integer minus a positive integer will always have a negative solution.
double check
I apologize for the confusion. It appears that there was an error in my response. The correct statement is:
A negative integer minus a positive integer will always have a negative solution.
but which one is it
I apologize for the incorrect response. Actually, the statement should be:
A positive integer minus a negative integer will always have a positive solution.
explain
I apologize for any confusion caused by my previous responses. Allow me to explain the correct answer in more detail:
When you subtract a positive integer from a negative integer, the result will always be negative.
For example, if you subtract -5 from 3, the calculation would be 3 - (-5), which can be rewritten as 3 + 5, resulting in 8. Since the answer is positive, it supports the statement that a positive integer minus a negative integer will always have a positive solution.
please triple check and explain simple
I apologize for any confusion caused by my previous responses. Here is the correct explanation in a simplified manner:
When subtracting integers, the sign of the solution depends on the signs of the integers being subtracted.
1. If you subtract a negative integer from a negative integer, the result will be negative. For example, if you subtract -3 from -5, the calculation would be (-5) - (-3), which simplifies to -5 + 3, resulting in -2. Therefore, a negative integer minus another negative integer will have a negative solution.
2. If you subtract a positive integer from a negative integer, the result will also be negative. For example, if you subtract 2 from -7, the calculation would be (-7) - 2, resulting in -9. Therefore, a positive integer minus a negative integer will have a negative solution.
3. If you subtract a negative integer from a positive integer, the result will be positive. For example, if you subtract -4 from 8, the calculation would be 8 - (-4), which simplifies to 8 + 4, resulting in 12. Therefore, a negative integer minus a positive integer will have a positive solution.
4. Lastly, if you subtract a positive integer from another positive integer, the result will be positive. For example, if you subtract 3 from 7, the calculation would be 7 - 3, resulting in 4. Therefore, a positive integer minus another positive integer will have a positive solution.
In summary, the correct statement is: A negative integer minus a positive integer will always have a negative solution.
Marsha purchased 42 red balloons for the party. She gave 13 away to children and used the rest for decoration. What equation could be used to identify the amount of balloons used for decoration?(1 point)
Responses
−42+13=−29
negative 42 plus 13 equals negative 29
−42−13=−55
negative 42 minus 13 equals negative 55
42−13=29
42 minus 13 equals 29
42+13=55
The equation that could be used to identify the amount of balloons used for decoration is:
42 - 13 = 29
This equation represents subtracting the amount of balloons given away (13) from the total amount purchased (42), resulting in the amount of balloons used for decoration (29).
Josie lost $10 on the way to the movies. She purchased a movie ticket for $8 and spent $5 on popcorn. Which expression could be used to identify how much money Josie lost/spent?(1 point)
Responses
−10−8−5
negative 10 minus 8 minus 5
10−8−5
10 minus 8 minus 5
−10−8+5
negative 10 minus 8 plus 5
−10+8−5
The expression that could be used to identify how much money Josie lost/spent is:
-10 - 8 - 5
This expression represents subtracting the amount of money lost on the way to the movies (-10), the cost of the movie ticket (-8), and the amount spent on popcorn (-5). The result will show the total amount of money Josie lost/spent.
Susie is trying to calculate 7−(−3). She uses the subtraction algorithm and finds that the answer is 10. She is confused about why her answer is bigger than either of her original numbers since she is subtracting. How could a number-line model be connected to the expression 7−(−3) to help Susie understand why her answer of 10 is correct?(1 point)

On a number line, find the distance from −3 to 7.
On a number line, find the distance from −3 to 7.
A number line can be depicted as a line that extends in both positive and negative directions, with points marking numerical values. To understand the expression 7−(−3), we can start at −3 on the number line and move in the positive direction until we reach 7.
Starting at point −3 and moving towards the positive direction, the distance between −3 and 7 is 10. Therefore, the answer to the expression 7−(−3) is indeed 10.
By visualizing the number line and seeing the distance between the points, we can help Susie understand why her answer of 10 is correct, even though she is subtracting a negative number.

Model #1:
An illustration shows a row of 4 solid circles with a negative sign in the middle of each circle. The last three circles are crossed out with diagonal lines.
Model #2:
An illustration shows a single solid circle with a negative sign in the middle. Next to it are 3 more negative circles, with 3 positive circles directly below. The 3 pairs of negative and positive circles are enclosed by vertical rectangles and are crossed out with diagonal lines.

Luca is modeling 4−(−3). He is showing that 4−(−3) is equivalent to 4+3.
In Model #1, Luca represents 4 as four solid circles with negative signs in the middle. Then, Luca crosses out three of these circles, representing (−3).
In Model #2, Luca represents 4 as a single solid circle with a negative sign in the middle. Then, Luca represents (−3) as three more negative circles. By enclosing three pairs of negative and positive circles and crossing them out, Luca is visually showing the addition of 4 and 3.
By connecting the two models, Luca is demonstrating that subtracting a negative number is equivalent to adding its positive counterpart.
