find each sum or difference:
3 - (-6) i got : 9
-23 + 9 i got : 14
-4 - (-9) i got : 5
-8 + 8 i got: 7
compare using <> =
-4 > -5
-2 < 0
|7| = |7|
-5 + 9 i got 4
-6 +(-3) i got -9
-7 - (-4) i got -3
-23 + 9 = -14 (not 14)
-8 + 8 = 0 (not 7)
Those two are the only ones I found incorrect.
sorry the problem s/b -1 + 8 = 7
sorry i meant to put -23 + 9 = -14
To find the sums or differences, follow these steps:
1. 3 - (-6): To subtract a negative number, change it to its positive form and then perform the addition. So, -(-6) becomes +6. Now, add 3 and 6: 3 + 6 = 9.
2. -23 + 9: Simply add -23 and 9: -23 + 9 = -14.
3. -4 - (-9): Similar to the first example, change -(-9) to +9. Then, subtract 4 and 9: -4 + 9 = 5.
4. -8 + 8: Add -8 and 8: -8 + 8 = 0.
To compare using the symbols <> =:
1. -4 > -5: Since -4 is greater than -5, the statement is true. So, -4 > -5.
2. -2 < 0: As -2 is smaller than 0, the statement is true. Hence, -2 < 0.
3. |7| = |7|: The absolute value of any number is always positive. So, both |7| and |7| give the result 7. Thus, |7| = |7|.
Now, let's complete the remaining calculations:
1. -5 + 9: Add -5 and 9: -5 + 9 = 4.
2. -6 + (-3): When adding a negative number, it is similar to subtracting. Therefore, -6 + (-3) equals -6 - 3, giving the result -9.
3. -7 - (-4): Convert -(-4) to +4. Then, subtract -7 and +4: -7 + 4 = -3.
So, the correct answers are:
1. 3 - (-6) = 9
2. -23 + 9 = -14
3. -4 - (-9) = 5
4. -8 + 8 = 0
5. -4 > -5
6. -2 < 0
7. |7| = |7|
8. -5 + 9 = 4
9. -6 + (-3) = -9
10. -7 - (-4) = -3
