Question

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

Answer 1

Answer: The mistake is improper use of distribution property.

Explanation:

It is given that
`3* (4+2)=12+2`.

We need to find the mistake.

The given expression is

`3* (4+2)`

Using distribution property, we get

`3* (4)+3*(2)`

`12+6`

So,
`3* (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.
