Travis has the following problem for homework: 82 - 16 x 4 + 18+ [(36/6) - 2]
His neighbor, Ted, says "just solve it working left to
right." Ted gets an answer of 51.
What is the correct answer? (Hint: Ted doesn't know
PEMDAS).

The correct answer is -4

Step-by-step explanation:

First you have to solve what is in the parenthesis. So do 36/6 which is 6 and then subtract 2 to get 4. Then you have to do the multiplication so 16 x 4 and you get 64. then you can go left to right. 82-64+18+4 and when you do that you get -4

To find the range, you order the list from least to greatest and then you subtract the lowest number from the highest. In this case, 39 - 19

To find the mean, you add up all of the numbers and then you divide the sum by the amount of numbers that are in the list. In this case, 220 / 8

The answers are 20 (range) and 27.5 (mean)
