Answer 1

use pemdas

Answer 2

First, we need to do the multiplication (3 times 16) and (2 times 21), starting from left to right:

2 + 48 - 42 - 3

Next, we subtract 42 from 48:

2 + 6 - 3

Finally, we add 2 and 6:

8

Therefore, the answer is B. 14.

Answer 3

Using PEMDAS, we need to perform the operations in the following order:

1. Parentheses (not applicable in this expression)
2. Exponents (not applicable in this expression)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

2 + (3 × 16) - (2 × 21) - 3

= 2 + 48 - 42 - 3

= 50 - 45

= 5

Therefore, using PEMDAS, the value of the expression is A. 5.
