Hello!
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].
You can feel free to let me know if you have any questions regarding this!
Thanks!
