When multiplying or dividing negative numbers remember this:
Same Signs \( \rightarrow \) Positive Answer
Different Signs \( \rightarrow \) Negative Answer
Example 1: Same signs (a positive multiplied by a positive) gives a positive answer:
\( 12 \times 6 = 72 \)
Example 2: Different signs (a positive multiplied by a negative) gives a negative answer:
\( 12 \times (6) = 72 \)
Example 3: Different signs (a negative divided by a positive) gives a negative answer:
\( (12) \div 6 = 2 \)
Example 4: Same signs (a negative divided by a negative) gives a positive answer:
\( (12) \div (6) = 2 \)
