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

Example: $$-5 - (-2) = -3$$

Subtract a negative number

### Practice Problems

Evaluate the following expression:
1. $$6 - (- 3) = ?$$ (
Solution
Solution: $$9$$
Details:
Let’s explore the patterns:

$$6 - (1) = 5$$

$$6 - (0) = 6$$

$$6 - (-1) = 7$$

$$6 - (-2) = 8$$

$$\color{red} 6 - (-3) = 9$$

Subtracting a negative number from a positive number result in a positive answer. This problem can also be rewritten as $$6 + 3 = 9$$.
)
2. $$4 - (- 4) = ?$$ (
Solution
Solution: $$8$$
Details:
Let’s explore the patterns:

4 $$- (1) = 3$$

4 $$- (0) = 4$$

4 $$- (-1) = 5$$

4 $$- (-2) = 6$$

4 $$- (-3) = 7$$

$$\color{red} 4 - (-4) = 8$$

Subtracting a negative number from a positive number results in a positive answer. This problem can also be rewritten as $$4 + 4 = 8$$.
