Recalling Integer Sign Rules in Corporate SOPs

As a newly hired financial analyst, you are tasked with documenting the standard operating procedures (SOPs) for batch processing ledger adjustments. In a short paragraph, state the fundamental mathematical rules for determining the final sign when multiplying or dividing two integers. Explicitly recall the rule for when two numbers have identical signs and the rule for when they have differing signs. Illustrate your recalled rules by referencing at least two of the following calculation examples: 115÷(5){}-115 \div (-5), 512{}5 \cdot 12, 9(7){}9(-7), or 63÷7{}-63 \div 7.
