Math subtraction worksheet with problems involving negative numbers.

To solve the given problems, we need to carefully handle the subtraction of integers, keeping in mind the rules for subtracting positive and negative numbers. Here are the solutions step by step:

General Rules for Subtracting Integers:

1. Subtracting a negative number is the same as adding its positive counterpart.
- \( a - (-b) = a + b \)
2. Subtracting a positive number is straightforward.
- \( a - b = a - b \)

Solutions:

#### 1) \( (-13) - (-5) \)
- Subtracting a negative is the same as adding its positive counterpart.
- \( (-13) - (-5) = (-13) + 5 = -8 \)
- Answer: \(-8\)

#### 2) \( (-9) - 16 \)
- Subtracting a positive number is straightforward.
- \( (-9) - 16 = -9 - 16 = -25 \)
- Answer: \(-25\)

#### 3) \( 7 - (-11) \)
- Subtracting a negative is the same as adding its positive counterpart.
- \( 7 - (-11) = 7 + 11 = 18 \)
- Answer: \(18\)

#### 4) \( 20 - 3 \)
- Subtracting a positive number is straightforward.
- \( 20 - 3 = 17 \)
- Answer: \(17\)

#### 5) \( (-18) - 14 \)
- Subtracting a positive number is straightforward.
- \( (-18) - 14 = -18 - 14 = -32 \)
- Answer: \(-32\)

#### 6) \( (-10) - (-10) \)
- Subtracting a negative is the same as adding its positive counterpart.
- \( (-10) - (-10) = (-10) + 10 = 0 \)
- Answer: \(0\)

#### 7) \( 15 - 2 \)
- Subtracting a positive number is straightforward.
- \( 15 - 2 = 13 \)
- Answer: \(13\)

#### 8) \( 8 - (-12) \)
- Subtracting a negative is the same as adding its positive counterpart.
- \( 8 - (-12) = 8 + 12 = 20 \)
- Answer: \(20\)

#### 9) \( (-20) - 9 \)
- Subtracting a positive number is straightforward.
- \( (-20) - 9 = -20 - 9 = -29 \)
- Answer: \(-29\)

#### 10) \( 17 - 6 \)
- Subtracting a positive number is straightforward.
- \( 17 - 6 = 11 \)
- Answer: \(11\)

#### 11) \( (-8) - (-14) \)
- Subtracting a negative is the same as adding its positive counterpart.
- \( (-8) - (-14) = (-8) + 14 = 6 \)
- Answer: \(6\)

#### 12) \( 12 - (-3) \)
- Subtracting a negative is the same as adding its positive counterpart.
- \( 12 - (-3) = 12 + 3 = 15 \)
- Answer: \(15\)

#### 13) \( 5 - 19 \)
- Subtracting a positive number is straightforward.
- \( 5 - 19 = -14 \)
- Answer: \(-14\)

#### 14) \( (-16) - 10 \)
- Subtracting a positive number is straightforward.
- \( (-16) - 10 = -16 - 10 = -26 \)
- Answer: \(-26\)

#### 15) \( 18 - (-4) \)
- Subtracting a negative is the same as adding its positive counterpart.
- \( 18 - (-4) = 18 + 4 = 22 \)
- Answer: \(22\)

#### 16) \( (-17) - (-1) \)
- Subtracting a negative is the same as adding its positive counterpart.
- \( (-17) - (-1) = (-17) + 1 = -16 \)
- Answer: \(-16\)
