Question

Find the mistake in the following : 3 x ( 4 + 2 ) = 12 + 2

Answer 1

Answer: The mistake is improper use of distribution property.

Step-by-step explanation:

It is given that $3\times (4+2)=12+2$.

We need to find the mistake.

The given expression is

$3\times (4+2)$

Using distribution property, we get

$3\times (4)+3\times(2)$

$12+6$

So, $3\times (4+2)=12+6$.

In the given calculation the 3 is not distributed properly because 3 is not multiplied with 2.

Therefore, the mistake is improper use of distribution property.
