Olympiad Test: Numerals - 1 - Class 2 MCQ

The number 47 has two digits. The tens digit is 4, which represents forty, and the ones digit is 7, which represents seven. Combining them gives the number name: Forty-seven.

Fifty-two is made of 50 + 2. The tens digit is 5 (50) and the ones digit is 2. Writing these together in digits gives 52.

Place value depends on the position of the digit. The digit 6 is in the tens place, so its place value is 6 × 10 = 60.

Expanded form breaks the number into the value of each digit: 3 hundreds = 300, 2 tens = 20, 6 ones = 6. Adding these gives 300 + 20 + 6.

Compare the digits from left to right. Tens place: 6 (67) and 7 (76). Since 7 tens > 6 tens, 76 is greater than 67.

Ascending order means arranging numbers from smallest to largest. Start with the smallest number 12, then 24, 36, and finally 48.

Ordinal numbers show position or rank. 1st = First, 2nd = Second, 3rd = Third, 4th = Fourth.

In Roman numerals, a smaller numeral before a larger numeral is subtracted. I (1) comes before X (10), so IX = 10 – 1 = 9.

12 = 10 + 2. Roman numeral for 10 is X, and 2 is II. Combining them gives XII.

The digit 3 is in the tens place. Place value = 3 × 10 = 30. Face value would be just 3, but place value considers the position.
