The average of 6 numbers is 6. This means that all 6 numbers have to add up to 36.

It doesn't matter what the numbers are, but in order to average out to 6, the sum of all the numbers divided by 6 has to equal 6.

The only thing that gives 6 when divided by 6 is 36.

Now, 3 is subtracted from 4 numbers, for a total of 12.

**(36-12)/6** tells us our new average

24/6

4 is the new average.
