Answer:
5
Step-by-step explanation:
Here, we are to use the order of priority to solve the question.
The order of priority looks like this;
BODMAS
where b represents brackets, o represents of, d represents division , m represents multiplication, a represents addition and s represents subtraction.
We are to use this one after the other with the preceding taking priority over the succeeding
Now let’s calculate!
2 + 3 × 16 − 2 × 21 − 3
we start with the multiplications
2 + 48 - 42 -3
The thing with subtraction and addition is that they can be used at the same time even though addition comes before subtraction.
Thus, we have 2 + 6 -3 = 8-3 = 5
Answer:
(A) 5
Step-by-step explanation:
The order of operations is BODMAS.
In the expression: 2 + 3 × 16 − 2 × 21 − 3
Multiplication comes first out of the other signs, so we evaluate first.
2 + 3 × 16 − 2 × 21 − 3=2+48-42-3
Next, we evaluate addition
2+48-42-3=50-42-3
Next, we evaluate subtraction
50-42-3=5
Therefore:
2 + 3 × 16 − 2 × 21 − 3=5
The correct option is A.
