What is the three-digit number formed by the digits 3, 1, and 4 in that order?

• A. 134
• B. 314
• C. 413
• D. 341

Answer: (B)

Understanding how numbers are built helps here: a three-digit number is read as hundreds, tens, and ones from left to right. Placing the digits 3, then 1, then 4 gives 3 hundreds, 1 ten, and 4 ones, which equals 300 + 10 + 4 = 314. That’s the number formed by those digits in that order. If you switch the digits, you’d get a different value (for example, starting with 1 would make 134, starting with 4 would be 413, etc.), so 314 is the correct arrangement.
