Sum of numbers = 40
Count of numbers = 4
Average = Sum/Count = 40/4 = 10
Average = (9+13)/2 = 22/2 = 11
2 + 2 + 9 = 13
9/11 minus 1/2 is 7/22.
9/11 - 1/2 = 18/22 - 11/22 = 7/22
6 is the average of 7,6,2, and 9 because 7+6+2+9=24, 24 divided by 4 is 6!

7-9=2 22 divide by 2=11 +13=24 boom im a legend
1/2 + 7/22 = 11/22 + 7/22 18/22 9/11.

-22 ÷ (3 + 2 x 4) + -7 = -9
3 x 22/9 = 66/9 = 22/3 or 7 and 1/3
