Arrange −3, 7, −11, 0 and −8 in ascending order.

Class 7Integers (Extended)Integers
  • A−11, −8, −3, 0, 7
  • B−3, −8, −11, 0, 7
  • C0, −3, −8, −11, 7
  • D7, 0, −3, −8, −11

Step-by-Step Solution

Ascending means smallest first. Among the negatives, the one furthest left on the number line is smallest: −11 < −8 < −3. Then comes 0, then 7. Writing the negative block as −3, −8, −11 sorts them like whole numbers and reverses that part; beginning with 7 is descending order, not ascending.
Answer: A) −11, −8, −3, 0, 7

Key idea: Multiplying more than two integers

Count the number of negative factors:
- **Even** number of negatives → product is positive.
- **Odd** number of negatives → product is negative.

Examples: has three negatives (odd) → negative. Compute the magnitude: . Result: −24.

has two negatives (even) → positive. Magnitude: . Result: +24.
