Answer 2

Let's solve the given mathematical expressions:

1. -12 · 5 = -60
2. -9 · (-24) = 216
3. 26 · (-12) = -312
4. -48 · (-1) = 48
5. – 57 · 0 = 0
6. -39 · 1 = -39
7. 72 : (-24) = -3
8. – 96 : (-8) = 12
9. – 49 : 7 = -7
10. – 97 : 1 = -97
11. 0 : (-42) = 0
12. – 54 : (-1) = 54

Remember the rules of multiplying and dividing with negative numbers:

• A negative number multiplied by a positive number is negative.
• A negative number multiplied by a negative number is positive.
• A positive number divided by a negative number is negative.
• A negative number divided by a negative number is positive.
• Division by 0 is undefined (except 0 divided by 0, which is also undefined).
