Answer
Correct Answer: 2000
Explanation
Concept & Formula
This simplification problem strictly follows the BODMAS rule (Brackets, Orders, Division, Multiplication, Addition, Subtraction). Operations must be executed left-to-right for Division and Multiplication in the sequence they appear if not bracketed, but Division takes precedence here.
Step-by-Step Solution
* Given expression:
$$ 4848 \div 24 \times 11 - 222 $$
* Step 1: Perform the Division first:
$$ \frac{4848}{24} = 202 $$
* (You can quickly see $48 \div 24 = 2$ and $48 \div 24 = 2$, putting a zero in between gives $202$).
* Step 2: Substitute back and perform the Multiplication:
$$ 202 \times 11 - 222 $$
$$ 202 \times 11 = 2222 $$
* Step 3: Perform the final Subtraction:
$$ 2222 - 222 = 2000 $$
Exam Strategy & Shortcut
**Multiplication by 11 Rule:**
When you reach $202 \times 11$, use the standard shortcut for multiplying by $11$: write the outer digits, and insert the sums of adjacent digits in between.
$2$, $(2+0)$, $(0+2)$, $2 \Rightarrow 2222$.
Subtracting $222$ from $2222$ immediately yields $2000$ visually without needing scratchpad math.
Common Pitfall
A major pitfall is executing the division incorrectly. Students often calculate $4848 \div 24$ as $22$ instead of $202$ by forgetting to insert the zero placeholder when bringing down the next digit. This leads to entirely wrong subsequent calculations.
Final Answer
**Therefore, the correct answer is 2000.**
