Question

Evaluate the following expression using the correct order of operations.
$2+1\times 2$

• A. 2
• B. 6
• C. 5
• D. 4

Answer 1

The correct option is D 4

$2+1\times 2$
As per the order of operations, we simplify an expression from the left and move to the right. While simplifying, the first operation that must be performed is multiplication or division, whichever appears first. This is followed by starting from left to right again and performing addition or subtraction, whichever appears first. First, let’s simplify
$\underset{–}{1\times 2}$
$2+\underset{–}{1\times 2}=2+2$
Now, simplify the addition.
$2+2=4$
