Your job is to follow the Order of Operations in which one always does the operations in a math problem in a sequence of:

**P arenthesis first**

**E xponents second**

**M ultiply or **

**Dvide next whichever is first in line left to right**

**A dd and **

**S ubtract last. Always do multipling and dividing ahead of adding and subtracting.**

**So take the numbers 8 4 2 1 and keep them in that order. You may add parenthesis , exponents, + - X or divide.**

**Now make those numbers =**

**0**

**1**

**2**

**3**

**4**

**5**

**6**

**7**

**8**

**9**

**10**

**11**

**12**

**13**

**14**

**15**

**16**

**17**

**18**

**19**

**20**

**An example would be ( 8-4) + 2 -1 = 5 since 8-4 goes first and that = 4 + 2 -1 which is 5**
