Here is the solution/answer to the brain teaser question of this week:

9 x 1 / 3 + 4 - 1 / 7 = ?
I am going to put parenthesis to make it easier to understand.
(9 x 1) / 3 + 4 - (1 x 7) = ?
Remember order of operations when you do this.
First multiply:
9 / 3 + 4 - 7 = ?
Then divide:
3 + 4 - 7 =?
Finally add and subtract left to right:
7 - 7 = 0
The answer is zero!

I hope you enjoy the brain teaser, the next one is coming Tuesday, September 3, 2013.

Order of Operations: 

How do you do a question like this?
 [(9-4)x(5+2)+5-17].
 I cant do a problem like this unless I had a set of directions. The solution is called "Please Excuse My Dear Aunt Sally!" This phrase is an easier way of remembering:

P-     simplify inside the parenthesis

E-     evaluate the exponents 

MD- multiply ans divide, left to right

AS-  add and subtract, left to right

It is vital that you memorize that. You will need it in Algebra I, Algebra II, and Geometry.

Here is an example:

3(5) + 4 - 1   First multiply 3(5)

15 + 4 - 1     Add and subtract from left to right

19 - 1

18

Here is the brain teaser math question;
(Some of you may find it easy, some of you may find it hard.)

9x1/3+4-1x7=?

The answer will be posted on Saturday, August 31st, 2013.
