What is the Roman numeral for 18?
- A.
XXVIII
- B.
XVIII
- C.
IVIII
- D.
VVVIII
Correct Answer
B. XVIIIExplanation
The Roman numeral for 18 is XVIII. Roman numerals are represented by combinations of letters from the Latin alphabet, primarily I, V, X, L, C, D, and M. To form the numeral for 18, 'X' (which stands for 10) is followed by 'VIII' (which stands for 8). When these values are added together—10 + 8—you get 18. This numeral system does not use repetitive or consecutive characters that would sum negatively when placed before larger values, except in specific cases (such as IV for 4 or IX for 9), thus XVIII is the correct notation for 18.Rate this question:

Correct Answer
D. 3056Explanation
To find the smallest 4-digit number using the digits 0, 3, 5, and 6, we need to consider the place values:
Thousand's place: Since it's a 4-digit number, we cannot start with 0, so the smallest possible digit for the thousand's place is 3.
Remaining digits: After placing 3 in the thousand's place, the remaining digits are 0, 5, and 6.
Ordering for smallest number: Arrange the remaining digits in ascending order after 3, which would be 0, 5, and 6.
Final number: Combining these, the smallest number is 3056.
Thus, the smallest 4-digit number you can form with the digits 0, 3, 5, and 6 is: 3056Rate this question:

2
- D.
1
Correct Answer
B. 4Explanation
A composite number is defined as a positive integer that has at least one positive divisor other than one or itself. The smallest single-digit composite number is 4. This is because 4 can be divided evenly by 1, 2, and 4, making it the first single-digit number that fits the definition of a composite number. Numbers like 2 and 1 are not composite; 2 is a prime number and 1 is neither prime nor composite as it only has one divisor, which is itself.Rate this question:
