How to solve cross sums


Solve cross sums is nothing but solving crossword puzzles which is simple game type learning which will attract kids to solve the math crossword puzzles. solve cross sums  from math contain problems that would be more challenging for kids to learn through games.  At the same time the students learn how to solve math problems. Let us solve cross sums.

Solve Cross Sums:

Examples:

Here given problem to solve cross sums.

Solution:

In the given problem

Let us solve the across puzzle first

Consider 1st row of A: 18 - 17 + 14 = 15.

Consider 3rd row of A: 17 + 1 -  4 = 14.

Consider 5th row of A: 5 - 3 + 20 = 22.

Let us solve the down puzzle first

Consider 1st column of A: 18 - 17 + 5 = 6.

Consider 3rd column of A: 17 + 1 - 3 = 15.

Consider 5th column of A: 14 - 4 + 20 = 30.

Consider 4th row and 4th column: 6 + 15 + 30  = 51

15 + 14 +22 = 51

The result for the 4th row and column remain the same as 51. This number 51 fills last box. From this we can say if the 4th row and column remain the same then puzzle answers are correct.

Solve Cross Sums:

Examples:

Here given problem to solve cross sums.

Solution:

In the given problem Consider the above problem

Let us solve the across puzzle first

Consider 1st row of A: 19 - 12 + 15 = 22.

Consider 3rd row of A: 12 + 11 -  3 = 20.

Consider 5th row of A: 12 - 3 + 17 = 26.

Let us solve the down puzzle first

Consider 1st column of A: 19 - 12 + 12 = 19.

Consider 3rd column of A: 12 + 11 - 3 = 20.

Consider 5th column of A: 15 - 3 + 17 = 29.



Consider 4th row and 4th column: 19 + 20 + 29  = 68

22 + 20 +26   = 68

The result for the 4th row and column remain the same as 68. This number 68 fills last box. From this we can say if the 4th row and 4th column remain the same then puzzle answers are correct.
