Understanding Negative Number Multiplication

Multiplying negative numbers might seem tricky at first, but it follows simple rules. A negative number is any number less than zero. When you multiply them, the sign of the result depends on how many negative numbers you are multiplying.

Basic Rules:

  • Negative × Negative = Positive: For example, (-2) × (-3) = 6.
  • Negative × Positive = Negative: For example, (-2) × 3 = -6.

When you multiply more than two negative numbers, count how many negative numbers there are. If there's an even count of negative numbers, the product is positive. If there's an odd count, the product is negative. For example:

  • (-1) × (-2) × (-3) = -6 (Three negative numbers - odd count, so negative product)
  • (-1) × (-2) × (-3) × (-4) = 24 (Four negative numbers - even count, so positive product)
