(-4) - (-1) =
Explanation
The given expression (-4) - (-1) can be simplified by subtracting the negative value inside the parentheses. A double negative becomes a positive, so (-4) - (-1) is equivalent to -4 + 1. When we add -4 and 1, we get -3 as the result.
2.
19 - (-9) =
Explanation
The given question is a subtraction problem where we subtract a negative number from a positive number. When we subtract a negative number, it is the same as adding its positive value. Therefore, subtracting -9 is equivalent to adding 9. So, 19 - (-9) can be rewritten as 19 + 9, which equals 28.
3.
(-2) -1 =
Explanation
The given expression is (-2) - 1. To solve this, we first simplify the expression inside the parentheses, which is -2. Then, we subtract 1 from -2. This results in -3. Therefore, the answer is -3.
4.
13 - 24 =
Explanation
The given equation 13 - 24 = -11 is solved by subtracting 24 from 13. When we subtract 24 from 13, we get -11. Therefore, the answer to the equation is -11.
5.
4 - 15 =
Explanation
When you subtract a larger number from a smaller one, the result is negative. For example, in the equation 4 - 15, since 15 is greater than 4, subtracting 15 from 4 gives you -11. This is because you're taking away more than you have, resulting in a negative value. So, 4 - 15 = -11.
6.
25 - (-23) =
Explanation
To solve 25 - (-23), you need to understand that subtracting a negative number is the same as adding a positive number. So, 25 - (-23) becomes 25 + 23. When you add 25 and 23, you get 48. Therefore, 25 - (-23) = 48. This is because subtracting a negative is like removing a negative, which results in a positive addition.
7.
-19 - 12 =
Explanation
When you subtract 12 from -19, you are essentially moving 12 units in the negative direction from -19 on the number line. This takes you to a position that is 31 units less than -19. Since you are moving in the negative direction, the result is negative, and the answer is -31.
8.
(-5) - 12 =
Explanation
The given expression is (-5) - 12. To simplify this expression, we subtract 12 from -5. When we subtract a positive number from a negative number, the result becomes more negative. So, -5 minus 12 is equal to -17.
9.
(-18) - (-24) =
Explanation
The given expression (-18) - (-24) can be simplified by removing the double negative sign. When subtracting a negative number, it is equivalent to adding the positive of that number. Therefore, (-18) - (-24) becomes (-18) + 24, which equals 6.
10.
3 - 7 =
Explanation
The given question asks for the result of subtracting 7 from 3. When we subtract 7 from 3, we get a negative number, specifically -4.
