Answer:
49
Explanation:
Following PEMDAS, which states:
1. parenthesis
2. exponents
3. multiplication/division (from left to right)
4. addition/subtraction (from left to right)
The first step would be 5÷5 because multiplication/division (in this case, we divide because reading the equation from left to right, 5÷5 comes first) comes before addition. 5÷5=1
1+4×12
Then we multiply 4×12 because multiplication/division comes before addition. 4×12=48
1+48
=49
