Answer:
(-3)× 4 = -12
4 × 3= 12
Step-by-step explanation:
The first expression is
[tex](-3)\cdot4[/tex]
We can write -3 = -1 × 3
[tex](-1\cdot3)\cdot4[/tex]
Apply associative property of multiplication
[tex]-1\cdot(3\cdot4)[/tex]
Multiply 3 and 4
[tex]-1\cdot(12)\\\\=-(1\cdot12)[/tex]
Finally, simplify by multiplying the numbers
[tex]=-12[/tex]
The Second expression is
4 × 3
= 12
