Answer: 44
Step-by-step explanation:
The algebraic hierarchy of operations tells us that we must first solve the multiplications before the addition and subtraction.
So in the expression that we have:
We must first solve the multiplication between 4 and 3 (wich is 12), we get the following:
Next, we can solve the substractions and additions, in the order we wish, we can do first the substraction (50-12=38):
And then the addition:
The result is 44.
