Explanation:
These types of puzzles are called math Sudoku, or KenKen.
As we can see, this is a 6 by 6 grid. In Sudoku, the numbers can't be repeated in any column or row. So, if there is a number 3 a column, that number can't be repeated in the column, so one of every number is in each column and row. Since this is a 6 by 6 grid. In each row and each column, there should be the numbers 1, 2, 3, 4, 5 and 6 exactly once.
The grid is divided into small shapes, each with a different number of squares. On the top left corner of each shape, there is an arithmetic equation. So for example, on the bottom left, there are 3 squares in a shape, which on its top left hand corner is the number 8 and a plus sign. Since in each square there should be a number, we need to find 3 numbers that add up to 8 between 1-6. The numbers can repeat in a shape, as long as they follow the row and column rules.
Here is an example:
This is more of a complicated one, but it has the same aspects.
