Answer:
60
Step-by-step explanation:
To find the solution, we need to use the order of operations.
If you recall PEMDAS, it gives the order of operations: Parenthesis, Exponents, Multiply & Divide, Add & Subtract.
This means that in this expression, the first thing that we must do is the multiplication that is within the parenthesis
[tex](10*4)+20\\\\(40)+20[/tex]
Now, all we need to do is add these together
[tex]40+20=60[/tex]
