1.

### What is the correct order of the following numbers from least to greatest: 12, 0, -1, -13, 4?

Answer: -13, -1, 0, 4, 12
Explanation:
The numbers in ascending order (from least to greatest) are:

-13, -1, 0, 4, 12

This order is determined by comparing the numerical values of each number. Starting with the smallest value (-13) and progressing to the largest value (12), the numbers are arranged in ascending order.
2.

### What is the value of -4 + (-5)?

Explanation:
The given expression is -4 + (-5). When adding two negative numbers, we add their absolute values and keep the negative sign. So, the absolute values of -4 and -5 are 4 and 5 respectively, and their sum is 9. Since both numbers are negative, the sum will be negative as well. Therefore, the correct answer is -9.
3.

### What is the value of -3 + 7?

Explanation:
The given expression -3 + 7 can be simplified by adding the two numbers together. -3 + 7 equals 4.
4.

### What is the value of  -2 - (-4)?

Explanation:
The given expression is -2 - (-4). To subtract a negative number, we change the subtraction sign to addition and change the sign of the number being subtracted. So, -2 - (-4) becomes -2 + 4. Adding -2 and 4 gives us 2. Therefore, the correct answer is 2.
5.

### What is the value of (-9) - 7?

Explanation:
To solve this, you perform subtraction.
-9 is a negative number, and when you subtract 7 from it, you're essentially moving further into the negative range on the number line.
-9 minus 7 is calculated as follows:
-9 - 7 = -16
So, the result of subtracting 7 from -9 is -16.
6.

### What is the value of h - 3, when h = 1?

Explanation:
To find the value of h - 3 for h = 1, we substitute the value of h into the expression. So, h - 3 becomes 1 - 3, which simplifies to -2. Therefore, the correct answer is -2.
7.

### What will be the negative value of –13 (minus thirteen)?

Explanation:
When you negate a negative number, it becomes positive. So, if you have -13 and you want its negative value, it is simply 13.
8.

### What is the predecessor of – 5?

Explanation:
The predecessor of a number is the number that comes immediately before it when counting in a sequential order. In this case, we are looking for the number that comes before -5. Since we are counting in the negative direction, the number immediately before -5 is -6. So, -6 is the predecessor of -5. The predecessor of -5 is -6. In mathematics, when you find the predecessor of a number, you subtract 1 from that number. So, -5 - 1 = -6.
9.

### What will the sum of these integers equal to? (- 8) + (+ 5) + (- 3) + (- 2)=

Explanation:
To find the sum, we add all the numbers together: -8 + 5 + (-3) + (-2) = -8 + 5 - 3 - 2 = -3 - 3 - 2 = -6 - 2 = -8. Therefore, the sum of the integer equation is -8.
10.

### What is the value of -9 - (-8)+(-6)?

Explanation:
To solve the expression -9 - (-8) + (-6), follow these steps:
Simplify the double negative:
-9 - (-8) is equivalent to -9 + 8.
-9 + 8 = -1.
-1 + (-6) is equivalent to -1 - 6.
Perform the subtraction:
-1 - 6 = -7.
Therefore, the value of the expression -9 - (-8) + (-6) is -7.
11.

### What is the successor of -9?

Explanation:
The successor of a number is the number that comes immediately after it when counting in a sequential order. In this case, we are looking for the number that comes after -9. Since we are counting in the negative direction, the number immediately after -9 is -8. So, -8 is the successor of -9. In mathematics, when you find the successor of a number, you add 1 to that number. So, -9 + 1 = -8.
12.

### What is the successor of 11+(-2)?

Explanation:
To find the successor of 11 + (-2), follow these steps:
11 + (-2) = 9.
Find the successor:
The successor of a number is the number that comes immediately after it.
Therefore, the successor of 9 is 10.
13.

### What is the value of -9+8+11+(-2)?

Explanation:
To find the value of -9 + 8 + 11 + (-2), follow these steps:
Add -9 and 8: -9 + 8 = -1
Add the result to 11: -1 + 11 = 10
Add the result to -2: 10 + (-2) = 8
Therefore, the value of -9 + 8 + 11 + (-2) is 8.
14.

### What is the value of a+(-3) when a=5?

Explanation:
To find the value of a+(−3)a + (-3)a+(−3) when a=5a = 5a=5, follow these steps:
Substitute the value of aaa into the expression: 5+(−3)5 + (-3)5+(−3)
Perform the addition: 5−3=25 - 3 = 25−3=2
Therefore, the value of 5+(−3)5 + (-3)5+(−3) is 2.
