When simplifying an expression that has more than one operation symbol, there is a special order you must follow.
Be careful in steps 3 and 4! Multiplication does not always come before division, nor does addition always come before subtraction! For example, in $$83\cdot~(4)\div~2+4$$ you would multiply before dividing because it is to the left of the division. Similarly, you would subtract before adding because it is to the left of the addition. 

Example 1: $83\cdot~(4)\div~2+4$ 8  3 • (4) ÷ 2 + 4 \ / 8  (12) ÷ 2 + 4 \ / 8  (6) + 4 \ / 14 +4 \ / 18 
Example 2: $20\div~(3+7)\cdot~2$ 20 ÷ (3 + 7) • 2
