### Order

1. 1. Order of Operations By David Kline
2. 2. What is Order of Operations <ul><li>                              </li></ul><ul><li>  </li></ul><ul><li>Order of operations is the order in which an expression is done </li></ul><ul><li>  </li></ul><ul><li>Order of Operation is done in the order called PEMDAS </li></ul><ul><li>  </li></ul><ul><li>Pemdas stands for Parentheses, Exponents, Multiplication, Division, addition, and subtraction </li></ul><ul><li>  </li></ul><ul><li>Pemdas can also be refered to as P lease E xcuse M y Dear A unt S ally </li></ul><ul><li>  </li></ul><ul><li>When doing an equation, it is best to put PEMDAS next to it so you won't get confused  </li></ul><ul><li>  </li></ul><ul><li>    </li></ul>
3. 3. P (Parentheses) <ul><li>Parentheses are used to group # together and mkes the inclosed problem get solved first </li></ul><ul><li>  </li></ul><ul><li>Here is an example: 5+2-(1+2) </li></ul><ul><li>  </li></ul><ul><li>The parentheses make the problem inside them be done first so the answer would be 4 </li></ul><ul><li>  </li></ul><ul><li>There can only be one parentheses in a sentence. The problem can't be (5)+8-(2)  </li></ul><ul><li>  </li></ul><ul><li>  </li></ul>
4. 4. E (Exponents) <ul><li>An exponent is number that is placed at the top right of another to mark how many times a number is multiplied </li></ul><ul><li>  </li></ul><ul><li>They first two numbers would be multiplied and then the answer you get from that would be multiplied by the next number and so on and so forth </li></ul><ul><li>  </li></ul><ul><li>If you were to write 25 the new number would be 32. Its just like 2x2x2x2x2=32   </li></ul>
5. 5. M(Multiplication) <ul><li>Multiplication is a process of finding the quantity by adding a number a certain number of times </li></ul><ul><li>  </li></ul><ul><li>To multiply, you need to take the number you want to multiply and the amount you want to multiply the number by. You would count the number by adding to it </li></ul><ul><li>  </li></ul><ul><li>For example: 4x5 is the same as 4+4+4+4+4. Its just adding the number a certain amount of times   </li></ul>
6. 6. D(Division) <ul><li>Division is a way to find how many times one number goes into another </li></ul><ul><li>  </li></ul><ul><li>To get the right answer when your dividing you have to look at the number and think how many times the number goes into the other. The amount that goes in is the answer </li></ul><ul><li>  </li></ul><ul><li>Example: 20/5=4 If you add 5to5 4 times then it would equal 20 but if you were to take 5 from 20 4 times it would be 0 so the answer to 20/5 would be 4 </li></ul><ul><li>  </li></ul><ul><li>  </li></ul>
7. 7. A(Addition) <ul><li>Addition is when you add numbers together to get a sum </li></ul><ul><li>  </li></ul><ul><li>all you have to do is add one number to the other </li></ul><ul><li>  </li></ul><ul><li>Example: 5+5=10 I added 5 to 5 and you would get 10 </li></ul><ul><li>  </li></ul><ul><li>  Adding numbers together is just like grouping them. When you group them together you have to count them and add them together </li></ul>
8. 8. S(Subtraction) <ul><li>Subtraction is when you take away from one number to get another </li></ul><ul><li>  </li></ul><ul><li>You use subtraction to get a factor. A factor is the answer you get when you subtract </li></ul><ul><li>  </li></ul><ul><li>Example: 5-3=2. 2 is the factor. </li></ul><ul><li>  </li></ul><ul><li>  </li></ul><ul><li>Now that you know about order of operations, I will give you a problem to answer: 5-2/8+(3x9) </li></ul>
