What does Sudoku denote?
-
Single numbers
-
Multiple numbers
-
Fractional numbers
-
Negative numbers
Correct Answer
A. Single numbersExplanation
Sudoku denotes single numbers because it is a logic-based number placement puzzle where the objective is to fill a 9x9 grid with digits so that each column, each row, and each of the nine 3x3 subgrids contains all of the digits from 1 to 9. The puzzle requires the player to use deduction and logic to determine the correct placement of numbers in each cell, ensuring that there is only one number in each cell.Rate this question:

What is the dimension of the square grid of Sudoku?
-
9 * 9
-
6 * 6
-
3 * 3
-
1 * 1
Correct Answer
A. 9 * 9Explanation
The dimension of a Sudoku grid refers to the number of rows and columns it has. In this case, the correct answer is 9 * 9, which means that the Sudoku grid is a square grid with 9 rows and 9 columns. Each row, column, and 3x3 square within the grid must contain the numbers 1-9 without repetition.Rate this question:

How many cells are available in the Sudoku game?
-
80
-
81
-
82
-
83
Correct Answer
A. 81Explanation
The correct answer is 81 because in a Sudoku game, there is a 9x9 grid consisting of 9 rows and 9 columns. Each row, column, and 3x3 subgrid contains 9 cells. Therefore, the total number of cells in the Sudoku game is 9 rows x 9 columns = 81 cells.Rate this question:

For classical Sudoku, what is "n" equal to?
-
2
-
3
-
4
-
5
Correct Answer
A. 3Explanation
In classical Sudoku, "n" refers to the size of the grid. It represents the number of rows, columns, and boxes in the puzzle. In this case, "n" is equal to 3, which means that the Sudoku grid consists of 3 rows, 3 columns, and 3 boxes in each row and column.Rate this question:

What is used in counting valid Sudoku grids?
-
Combinatorics
-
Binomial expansion
-
Probability
-
Combined factors
Correct Answer
A. CombinatoricsExplanation
Combinatorics is the branch of mathematics that deals with counting and arranging objects. In the context of counting valid Sudoku grids, combinatorics is used to determine the number of possible arrangements of numbers that satisfy the rules of Sudoku. It involves analyzing the different combinations and permutations of numbers in order to calculate the total number of valid grids. Binomial expansion, probability, and combined factors are not directly applicable to counting valid Sudoku grids, making combinatorics the correct answer.Rate this question:

What is the representation of rank "n?"
-
2n
-
N^2 × n^2
-
2(n) × 2(n)
-
N × n
Correct Answer
A. 2(n) × 2(n)Explanation
The representation of rank "n" is 2(n) × 2(n). This means that the rank "n" is multiplied by 2 and then multiplied by 2 again. This results in a representation that is equal to 2 raised to the power of "n" multiplied by 2 raised to the power of "n".Rate this question:

For rank "n," what are the numbers used to fill the grid?
-
1, 2, 3, ..., 2n
-
1, 2, 3, ..., n-2
-
1, 2, 3, ..., n^2
-
1, 2, 3, ..., n
Correct Answer
A. 1, 2, 3, ..., n^2Explanation
The numbers used to fill the grid are 1, 2, 3, ..., n^2. This is because the question asks for the numbers used to fill the grid for rank "n." The notation "1, 2, 3, ..., n^2" represents a sequence of numbers starting from 1 and incrementing by 1 until reaching n^2. Therefore, this sequence includes all the numbers needed to fill the grid.Rate this question:

What do we call the constraint on the rows, columns, and blocks?
-
One goal
-
One target
-
One task
-
One ruleÂ
Correct Answer
A. One ruleÂExplanation
The constraint on the rows, columns, and blocks in a puzzle is referred to as "One rule". This implies that each row, column, and block must contain only one instance of each number from 1 to 9. This constraint is a fundamental rule in solving puzzles such as Sudoku, ensuring that all numbers are placed correctly and without repetition in each row, column, and block.Rate this question:
