### Why do we need a standard way to simplify mathematical expressions or equations?

**To avoid confusion!!**### Example:

### Let's think

**...**8 plus 2 equals 10### 10 times 3 equals 30. That's the answer!!

**OR***Still thinking***...**### 2 times 3 equals 6

### 6 plus 8 equals 14. What, another answer.

**CONFUSION**### is settling in.

*Still thinking***...**, maybe the operations must be performed in a specific order?

### Simplify any expression in a grouping symbol.

**[ 2 + (8-3) + 5 ]****(3 - 5) / 6 * 7**### Simplify expressions with exponents.

**4^3 + (6 - 4)^2**### Carry out multiplication or division from left to right.

**6 * 3 / 9 * 8**### Lastly, simplify addition or subtraction from left to right.
