Show answer & explanation
Correct answer: A
To evaluate the expression [2345 + (315 × 2)] – (336 – 21), you must follow the order of operations, commonly referred to as BODMAS or PEMDAS.
Step-by-Step Calculation
Solve the innermost parentheses first:
(315 × 2) = 630
The expression now looks like: [2345 + 630] – (336 – 21)
Solve the calculations within the brackets and remaining parentheses:
[2345 + 630] = 2975
(336 – 21) = 315
Perform the final subtraction:
2975 – 315 = 2660
