Question 1145892
What is the general rule of adding missing parentheses and correct order  of ioeration

Here are 2 problems missing parentheses please help and add

1.  80-36 /  2+6 - 2 x 5 + 1 = 44
2.  3x5 + 4  - 2 x 2 + 6 - 4 = 15
<pre><b>1.</b>    80 - 36 ÷ (2 + 6 - 2) * (5 + 1) = 44  
      80 - 36 ÷ 6 * 6 = 44 
     {{{highlight_green(matrix(1,7, 80 - (36/6) * 6, "=", 80 - (36/cross(6)) * cross(6), "=", 80 - 36, "=", 44))}}} 
<b>2.</b>    3 * 5 + 4 - 2 * 2 + 6 - 4 = 15 
      3 * (5 + 4) - [2 * (2 + 6) - 4] = 15 
     {{{highlight_green(matrix(1,7, 3(9) - (2 * 8 - 4), "=", 3(9)  -  (16  -  4), "=", 27 - 12, "=", 15))}}}
<b>BTW:</b>  Edwin's # 2 needs correction, NOT # 1. It s/b 3 * 5 as opposed to 2 * 5
