Answer 2

(-3)× 4 = -12

4 × 3= 12

Explanation:

The first expression is

`(-3)\cdot4`

We can write -3 = -1 × 3

`(-1\cdot3)\cdot4`

Apply associative property of multiplication

`-1\cdot(3\cdot4)`

Multiply 3 and 4

`-1\cdot(12)\\\\=-(1\cdot12)`

Finally, simplify by multiplying the numbers

`=-12`

The Second expression is

4 × 3

= 12
