20 – 578 ÷ 4 × 100 = ____________

To solve the expression (20 – 578 ÷ 4 × 100), we need to follow the order of operations (PEMDAS/BODMAS). This means we perform division and multiplication before subtraction.

1. First, do the division:

(578 ÷ 4 = 144.5)

2. Next, multiply that result by 100:

(144.5 × 100 = 14450)

3. Now, subtract that from 20:

(20 – 14450 = -14430)

None of the options a), b), c), or d) match the result exactly, so please double-check the question and context.
