Solution
The rule of the diamond problem is given below
I will label the question as follow
Basically, we need to find a and a + b
[tex]\begin{gathered} a=\text{?} \\ b=-1 \\ ab=6 \\ a+b=\text{?} \end{gathered}[/tex]
From the above info
[tex]\begin{gathered} ab=6 \\ a(-1)=6 \\ -a=6 \\ a=-6 \end{gathered}[/tex][tex]a+b=-6+(-1)=-7[/tex]
The diamond problem solution is
