Multiplying & dividing (sign rules)

For × and ÷, only signs matter. Just count the minus signs:

  • (+) × (+) = +    e.g., 4 × 3 = 12
  • (+) × (–) = –    e.g., 4 × (–3) = –12
  • (–) × (+) = –    e.g., (–4) × 3 = –12
  • (–) × (–) = +    e.g., (–4) × (–3) = 12

Same rules for division.

Example
(–2) × (–3) × (–4) = +6 × (–4) = –24.
Three negatives (odd) → answer is negative.
💡 Tip:Even number of minuses → positive. Odd number → negative.
