1 + (−3)

### Explanation

Step 1:

Rule: If the numbers are of opposite signs, find their difference and put the sign of the greater number

Step 2:

Difference of [1, 3] = 3 – 1 = 2;

Sign of greater number is –. So, 1 + (−3) = −2

Q 2 - Add the following integers:

−1 + (−2)

### Explanation

Step 1:

Rule: If the numbers are of same sign, we add them and keep the sign on the sum.

Step 2:

Sum of [1, 2] = 1 + 2 = 3; Sign of numbers is –.

So, −1 + (−2) = −3

Q 3 - Add the following integers:

3 + (−3)

### Explanation

Step 1:

Rule: If the numbers are of opposite signs, find their difference and put the sign of the greater number

Step 2:

Difference of [3, 3] = 3 – 3 = 0;

So, 3 + (−3) = 0

Q 4 - Add the following integers:

−4 + (−2)

### Explanation

Step 1:

Rule: If the numbers are of same sign, we add them and put their sign on the sum.

Step 2:

Sum of [4, 2] = 4 + 2 = 6; Sign of numbers is –.

So, −4 + (−2) = −6

Q 5 - Add the following integers:

3 + (−7)

### Explanation

Step 1:

Rule: If the numbers are of opposite signs, we find their difference and put the sign of the greater number

Step 2:

Difference of [3, 7] = 7 – 3 = 4; Sign of greater number is –.

So, 3 + (−7) = −4

Q 6 - Add the following integers:

−4 + (−6)

### Explanation

Step 1:

Rule: If the numbers are of same sign, we add them and put their sign on the sum.

Step 2:

Sum of [4, 6] = 4 + 6 = 10; Sign of numbers is –.

So, −4 + (−6) = −10

Q 7 - Add the following integers:

−3 + (−9)

### Explanation

Step 1:

Rule: If the numbers are of same sign, we add them and put their sign on the sum.

Step 2:

Sum of [3, 9] = 9 + 3 = 12; Sign of numbers is –.

So, −3 + (−9) = −12

Q 8 - Add the following integers:

2 + (−5)

### Explanation

Step 1:

Rule: If the numbers are of opposite signs, we find their difference and put the sign of the greater number.

Step 2:

Difference of [5, 2] = 5 – 2 = 3; Sign of greater number is −.

So, 2 + (−5) = −3

Q 9 - Add the following integers:

7 + (−6)

### Explanation

Step 1:

Rule: If the numbers are of opposite signs, we find their difference and put the sign of the greater number.

Step 2:

Difference of [7, 6] = 7 – 6 = 1; Sign of greater number is +.

So, 7 + (−6) = +1 = 1

Q 10 - Add the following integers:

−5 + (−8)

### Explanation

Step 1:

Rule: If the numbers are of same sign, we add them and put their sign on the sum.

Step 2:

Sum of [5, 8] = 5 + 8 = 13; Sign of numbers is –.

So, −5 + (−8) = −13
