Explanation: This question's it's about the order of operations. It's stands for: P-parenthesis, E-exponents, M-multiply, D-divide, A-add, and S-subtract. It can also go left to right.
First, you multiply and divide left to right.
[tex]4*12=48[/tex]
[tex]48+36/9[/tex]
[tex]36/9=4[/tex]
Then, you add left to right.
[tex]48+4=52[/tex]
[tex]\boxed{=52}[/tex]
Hope this helps!
Thanks!
Have a great day!
