# Negative numbers and absolute value

### Subtraction involving negative numbers

• Subtracting a positive number produces a smaller number, for example $$-4 - 3 = -7$$ and $$3 - 5 = -2$$.
• Subtracting a negative number is the same as adding the number, for example, $$3-(-5) = 3+5 = 8,$$ and $$-4-(-3) = -4+3 = -1$$.
