How to solve:

1. Perform operations inside parentheses & exponentiations first. If there are more than such operations, do the one on the left first and work to the right.

2. Perform multiplications and divisions. If there are more than one of these, do the one on the left first and work to the right.

3. Perform additions and subtractions. If there are more than one of these, do the one on the left first and work to the right.

Example.
Simplify: 12 + 6 ÷ 3 - 4 · 2.       (12 + 6) ÷ 3 - 4 · 2.
Operation with the highest precedence: Division       Addition (in Parentheses)
Simplifies to: 12 + 2 - 4 · 2       18 ÷ 3 - 4 · 2
Operation with the highest precedence: Multiplication       Division
Simplifies to: 12 + 2 - 8       6 - 4 · 2
Operation with the highest precedence: Addition       Multiplication
Simplifies to: 14 - 8       6 - 8
Operation with the highest precedence: Subtraction       Subtraction
Simplifies to: 6       -2
