Answer:
Student B
Step-by-step explanation:
B (Brackets)
O (Of)
D (Division)
M (Multiplication)
A (Addition)
S (Subtraction)
BODMAS is the rule to follow while solving a problem. It tells us that we first solve the brackets, then the of (multiplication) and so on.
In the problem 4 + (5 x 9)
Firstly we solve brackets.
Then Addition.
⇒4 + 45
⇒49
Student B did the same thing. That is why he is correct.
But Student A did not follow BODMAS. He will end up with the wrong answer. Maybe you can teach him.
