To solve this problem, we are going to use PEMDAS. First, let's write the problem. [tex]22\left(4+16\right)-78\cdot \:3[/tex] Parenthesis first, [tex]4+16=20[/tex] [tex]=22\cdot \:20-78\cdot \:3[/tex] Multiply and Divide from left to right. [tex]22\cdot \:20=440[/tex] [tex]=440-78\cdot \:3[/tex] We got another multiplication operation left... [tex]-78\cdot \:3=-234[/tex] [tex]=440-234[/tex] Subtract. [tex]440-234=206[/tex] [tex]=206[/tex]
Our final answer would be [tex]206[/tex].
