Respuesta :

(2*6)/(2+1)=4

this way the numbers in the parenthesis go first and are divided correctly
2 x 6 ÷ 2 + 1   You can try grouping this three different ways and solving.

(2 x 6) ÷ 2 + 1   Multiply
    12 ÷ 2 + 1      Divide
        6 + 1          Add 
           7

2 x (6 ÷ 2) + 1   Divide
    2 x 3 + 1       Mutliply
       6 + 1          Add
          7

2 x 6 ÷ (2 + 1)   Add
   2 x 6 ÷ 3       Multiply
     12 ÷ 3          Divide 
         4

The correct way to group this equation to equal 4 is 2 x 6 ÷ (2 + 1) .
