Question

Show how to multiply 6 x 298 using friendly numbers and then use properties and mental math.

Answer 1

I personally don't like this common core stuff but I think I can answer
friendly numbers
you can make 298 into the 'friendly number' of 300
300 times 6=1800

the friendly number answer is 1800
mental math tells us that it is 1788
close enough

Answer 2

For this case we have the following multiplication:

`image`

We can rewrite this operation to facilitate the calculation.

We have then:

`image`

From here, we apply the distributive property.

We have then:

`image`

Rewriting we have:

`image`

Finally adding all the numbers we have:

`image`

Answer:

The value of 6 * 298 is 1788 and the calculations can be provided as follows:

`6 * 298 = 6 * (200 + 90 + 8)`
