Order to solve Mathematical Operations:

Example:

Solve the following equation:

(4 - 2) + (3 x 4) - (10 ÷ 5) - 6 =  ____________

Solution:

a.         Perform math operations inside each set of parentheses.

4 - 2 = 2

3 x 4 = 12       

10 ÷ 5 = 2

b.         Perform addition & subtraction operations from left to right.

c.         The final answer is 2 + 12 - 2 - 6 = 6

There might be cases where various operations would be performed inside multiple sets of parentheses.    In  that  case  you  must  perform  all  operations  inside  the  innermost  set  of parentheses and work outward.  You must carry on observing the hierarchical rules throughout the problem. In addition sets of parentheses might be implies by brackets, [ ].
