1. Division with negative numbers:
A derivation
1  1 = 1
-1  1 = -1 : Identity operation
-1  -1 = ?
1 (-1) = ?

2. Division with negative numbers:
A derivation  1 -1
-1  -1 = ? 1 -1 ? ?
= -1  ?
The relationship between
multiplication and division

3. Division with negative numbers:
A derivation  1 -1
-1  -1 = ? 1 -1 ? ?
= -1  ?
-1 = -1  1

4. Division with negative numbers:
A derivation  1 -1
-1  -1 = ? 1 -1 ? 1
= -1  ?
-1 = -1  1

5. Division with negative numbers:
A derivation  1 -1 1 -1 ?
1  -1 = ? 1
0  -1 = 0
(1 – 1)
[1 + (-1)]

6. Division with negative numbers:
A derivation  1 -1 1 -1 ?
1  -1 = ? 1
0  -1 = 0
[1 + (-1)]  -1 = 0
-1  -1 = 1

7. Division with negative numbers:
A derivation  1 -1 1 -1 ?
1  -1 = ? 1
0  -1 = 0
(1  -1) + 1 = 0 -1

8. Division with negative numbers:
A derivation  1 -1 1 -1 -1
1  -1 = ? 1
0  -1 = 0
(1  -1) + 1 = 0 -1

9. Division with negative numbers:
A derivation  1 -1  1 -1
