To evaluate the expression \(2 + 3 \times 16 - 2 \times 21 - 3\) using the order of operations (also known as PEMDAS/BODMAS), we first perform multiplication and then carry out addition and subtraction from left to right.
1. Calculate the products:
- \(3 \times 16 = 48\)
- \(2 \times 21 = 42\)
So the expression becomes:
\[
2 + 48 - 42 - 3
\]
2. Perform the addition and subtraction from left to right:
- \(2 + 48 = 50\)
- \(50 - 42 = 8\)
- \(8 - 3 = 5\)
Thus, the value of the expression is:
\[
\boxed{5}
\]
