When you're combining 'like terms', look for all the terms that end with 'ab'.
Then add all the numbers that have 'ab' after them.

Add all values together:

There are 8 numbers in the data set.
40 ÷ 8 = 5
The mean of the data is 5.
<h3>
The Median:</h3>
Order the numbers in ascending order.
4, 4, 4, 4, 5, 5, 6, 8
There is no exact middle number.

The median of the data is 4.5.
<h3>The Mode:</h3>
'4' appears the most in the data set.
4, 4, 4, 4, 5, 5, 6, 8
The mode of the data is 4.
You multiply 6 and 7 then you subtract what you get by 28
