# Starting from (–1) × 5, write various products showing some pattern to show (–1) × (–1) = 1

**Solution:**

(-1) × 5 = -5

(-1) × 4 = -4

(-1) × 3 = -3

(-1) × 2 = -2

(-1) × 1 = -1

(-1) × 0 = 0

(-1) × -1 = 1

Thus, it is clear that when we multiply a negative integer by a positive integer the result is a negative integer whereas if we multiply a negative integer by a negative integer the result is always a positive integer
