Given the following expression:
[tex]5\mleft(67-94\mright)-12[/tex]You can apply the steps shown below in order to find the result:
Step 1. You must solve the subtraction inside the parentheses (Since 94 is greater than 67 and it is also negative, the difference will be negative). Then:
[tex]=5(-27)-12[/tex]Step 2. Solve the multiplication, but first you must remember the following Sign rules for multiplication:
[tex]\begin{gathered} -_{}\cdot-=+ \\ +\cdot+=+ \\ -\cdot+=-_{} \\ +\cdot-=- \end{gathered}[/tex]Then:
[tex]=-135-12[/tex]Step 3. Since both numbers are negative, you must add them. The result will be negative too.
The result is:
[tex]=-147[/tex]
