Which is true when a negative nuber is subtracted from a positve number?
A.the difference is always 0
B.the difference is always positive
C.the difference is always negative
D.the difference could be negative or positive
*i need examples to
Try some examples.
+ 8 - (-8)
Remember when you subtract, you add the opposite in algebra
+8 + (+8) = 16
+ 10 - (-4) = "
Look for a pattern.
B always positive
for example, this would be positive number - negative number = positive number + - - positive number = positive number
3 (positive number ) - (-14) (negative number) = 3 --14 = 3+14 = 17. btw it cant be 0 because the first number is positive
ty both so much

When a positive number is subtracted from a negative number, the difference is always negative. However, when a negative number is subtracted from a positive number, the difference could be either negative or positive.
To understand this concept better, let's consider some examples:
Example 1: 8 - (-3) = 8 + 3 = 11
In this case, a negative number (-3) is subtracted from a positive number (8). The difference is positive (+11).
Example 2: 5 - (-7) = 5 + 7 = 12
Again, a negative number (-7) is subtracted from a positive number (5). The difference is positive (+12) in this case as well.
Example 3: 4 - (-6) = 4 + 6 = 10
Once more, a negative number (-6) is subtracted from a positive number (4). The difference is positive (+10).
Example 4: 2 - (-4) = 2 + 4 = 6
And yet again, a negative number (-4) is subtracted from a positive number (2). The difference is positive (+6).
These examples demonstrate that when subtracting a negative number from a positive number, the difference can indeed be positive. Therefore, the correct answer to the question is option D: the difference could be negative or positive.
