What is -720 divided by -8?

• A. -90
• B. 90
• C. 720
• D. -720

Answer: (B)

Division signs: when you divide two numbers with the same sign, the result is positive. Here, -720 divided by -8 cancels the negatives, leaving 720 ÷ 8. Since 8 × 90 = 720, the quotient is 90. So the result is positive 90. The other options don’t fit because they’re either negative (the signs don’t produce a negative result here) or they don’t reflect dividing by 8 (for example, 720 would imply a different operation, and -720 would keep the negative sign).
