Quote:

fill in each blank with the symbols +,-,*,/ and () to make the equation true
7 3 -4=-5

how are we supposed to know what the blanks are?

um trial and error

7+(3x-4)=-5
7+(-12)=-5
7-12=-5
-5=-5
you don't have to put the parenthesis, it's just there to make it a bit more obvious if you are still learning PEMDAS
