Digit Matrix is a collection of interesting mathematics exercises. This APP can improve the ability of calculation and logical reasoning, and cultivate mathematical thinking. It includes topics ranging from simple to very difficult. It is a good helper in learning mathematics or training the brain.
Feature:
Computing and Logical Reasoning
Fifteen types. Infinite exercises
Different Difficulties
Easy to get started
Five themes
Contents:
1. Arithmetic Square
Place the numbers from 1 to 9 into the cells (a different single number in each cell) so that the indicated equations are correct. Evaluate from left-to-right and top-to-bottom (ignore the usual precedence of the operators).
2. Chains
Enter the numbers from 1 to X in the squares, once each, so that the given equations are correct. (Each equation begins at one square and ends at the next square; X is the total number of squares.)
3. SUMS
Place a number from 1 to N into each cell. (N is the total number of cells in the grid.) Every cell must contain a different number. The numbers outside the grid, when given, indicate the sum of the numbers in the corresponding row, column, or diagonal.
4. Coins
Place one coin into each cell such that the sum of the coins in each row and column matches the number to the left and the top. the same denomination may be used multiple times in each row or column.
5. Hundred
A square grid whose cells are to be filled by some digits. The task is to fill additional digits in required cells such that the sum of numbers in each row and each column equals to 100.
6. Antimagic Square
Place numbers from 1 to 2*N (N is the number of cells per side) into the cells so that there are exactly two numbers in each row, column and main diagonal. The sums of the two numbers are shown around the grid.
7. Products
Place numbers from 1 to 2*N (N is the number of cells per side) into some cells so that each number is in exactly one cell, and no cell has more than one number. Each row and each column must contain exactly two numbers. Numbers outside the grid are the product of the two numbers in that row or column.
8. Products (Off-by-One)
Place numbers from 1 to 2*N (N is the number of cells per side) into some cells so that each number is in exactly one cell, and no cell has more than one number. Each row and each column must contain exactly two numbers. Numbers outside the grid are 1 more or 1 less than the product of the two numbers in that row or column.
9. Addends
Select Specified quantity of numbers from a given number set. Each number can not selected more than once. The sum of selected numbers must same as the given value.
10. Equality
Delete Specified quantity of squares so that what remains is a correct equation. Use standard order of precedence (multiplication and division before addition and subtraction).
11. Alphametic Square
Each letter represents a different digit. Figure out which letter corresponds to which digit so that all equations are true. Multi-digit numbers cannot start with the digit 0.
12. Matches Arithmetic
Remove, Add or Move one to three matches so that the matches express a correct arithmetic equality. Click the match to remove it. Click the empty position to add the match.
13. Digit Twins
Two numbers are connected by up to three line segments, and the two numbers are divided by their greatest common divisor at the same time. If the quotient is 1, the number will be eliminated. All numbers on the board need to be eliminated.
14. Divisor and multiple
Numbers are added to 2 queues alternately. 2 groups of numbers are divided by their greatest common divisor in turn. Eliminate the number If the quotient is 1.
15. Numeric Factor Path
On the board, if any two adjacent numbers have a common divisor greater than 1, they can be connected, and only one line can be connected between the two adjacent numbers. The final goal is to connect all the numbers into a non-intersecting path.
