Answer :

Sure, let's go through each problem step-by-step:

### 1. Find: [tex]\((-25) + (-18)\)[/tex]

When you add two negative numbers, you add their absolute values together and keep the negative sign.

[tex]\[ (-25) + (-18) = - (25 + 18) = -(43) = -43 \][/tex]

So, the result is [tex]\(-43\)[/tex].

### 2. Subtract [tex]\(-95\)[/tex] from [tex]\(0\)[/tex]

Subtracting a negative number is the same as adding its positive counterpart.

[tex]\[ 0 - (-95) = 0 + 95 = 95 \][/tex]

So, the result is [tex]\(95\)[/tex].

### 3. Find the difference: [tex]\((-15) - (21)\)[/tex]

To find the difference between [tex]\(-15\)[/tex] and [tex]\(21\)[/tex], you subtract [tex]\(21\)[/tex] from [tex]\(-15\)[/tex]:

[tex]\[ (-15) - 21 = -15 - 21 = -36 \][/tex]

So, the result is [tex]\(-36\)[/tex].

### 4. Use the number line to find:
#### i) [tex]\(4 + (-6)\)[/tex]

Adding a negative number is equivalent to subtracting the positive value:

[tex]\[ 4 + (-6) = 4 - 6 = -2 \][/tex]

So, the result is [tex]\(-2\)[/tex].

#### ii) [tex]\((-6) + (-3)\)[/tex]

Adding two negative numbers results in a negative number whose absolute value is the sum of the absolute values of the addends:

[tex]\[ (-6) + (-3) = - (6 + 3) = -9 \][/tex]

So, the result is [tex]\(-9\)[/tex].

### 5. The sum of two integers is [tex]\(-23\)[/tex]. If one of them is [tex]\(12\)[/tex], find the other.

Let [tex]\(x\)[/tex] be the other integer.

Given:
[tex]\[ 12 + x = -23 \][/tex]

To find [tex]\(x\)[/tex]:

[tex]\[ x = -23 - 12 = -35 \][/tex]

So, the other integer is [tex]\(-35\)[/tex].

### 6. Write the following integers in ascending order: [tex]\(-9, -24, 26, -2, -11, 18, 9\)[/tex]

To arrange these integers in ascending order, we list them from the smallest to the largest:

[tex]\[ -24, -11, -9, -2, 9, 18, 26 \][/tex]

So, the sorted list is [tex]\([-24, -11, -9, -2, 9, 18, 26]\)[/tex].
