Check out Bas Rutten's Liver Shot on MMA Surge: http://bit.ly/MMASurgeEp1 In this video, Mahalo math expert Julie Clark gives you a quiz to test your knowledge of the basics of order of operations. Question 1 --------------------------------------------------------------------- Solve this problem using the correct order of operations: 15 - 2 + 8 1. 5 2. 21 If You Chose #1 --------------------------------------------------------------------- You're incorrect. Here's how to do the problem correctly: Since there are no parentheses, exponents or multiplication or division portions, all you need to do is addition and subtraction from left to right. Since 15 minus two is 13, you are left with 13 plus eight. That equals 21, which is your answer. If You Chose #2 --------------------------------------------------------------------- You're correct. Here's the process you should have used: Since there are no parentheses, exponents or multiplication or division portions, all you need to do is addition and subtraction from left to right. Since 15 minus two is 13, you are left with 13 plus eight. That equals 21, which is your answer. Question 2 --------------------------------------------------------------------- Solve the following problem using the correct order of operations: 24 - 8 - 6. 1. 10 2. 22 If You Chose #1 --------------------------------------------------------------------- You're correct. Here's the process you should have used: Since there are no parentheses, exponents or multiplication or division portions, all you need to do is addition and subtraction from left to right. Since 24 minus eight is 16, you are left with 16 minus six. That equals 10, which is your answer. If You Chose #2 --------------------------------------------------------------------- You're incorrect. Here's the process you should have used: Since there are no parentheses, exponents or multiplication or division portions, all you need to do is addition and subtraction from left to right.

Here's how to do the problem so that you get the right answer: First,?substitute?all variables in the equation with the numbers given. That gives you (2 x 1 + 4 x 2) ?. Order of operations tells you to do whatever is inside the parentheses first. Since there are no exponents inside the parentheses, start doing the multiplication and division from left to right. Two times one is two, and four times two is eight. Now you have (2 + 8)?. The next step is to do all addition and subtraction, so two plus eight is 10. The last step is to square 10, which gives you 100. If You Chose #2 --------------------------------------------------------------------- You're correct!
