You can put this solution on YOUR website!
1. 80-36/(2+6-2)×(5+1) = 44
2. |2×(5+(4-(2×2+6)-4))| = 15
I had to use absolute value on that one! lol

My correction to Edwin's #1


((80-36)/(2+6-2))×(5+1) = 44 


Or, in more details,  %28%2880-36%29%2F%282%2B6-2%29%29%2A%285%2B1%29 = %2880-36%29%2A%28%285%2B1%29%2F%282%2B6-2%29%29 = 44%2A%286%2F6%29 = 44*1 = 44.

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
1.    80 - 36 ÷ (2 + 6 - 2) * (5 + 1) = 44  

      80 - 36 ÷ 6 * 6 = 44 

      

2.    3 * 5 + 4 - 2 * 2 + 6 - 4 = 15 

      3 * (5 + 4) - [2 * (2 + 6) - 4] = 15 

     

BTW:  Edwin's # 2 needs correction, NOT # 1. It s/b 3 * 5 as opposed to 2 * 5
