Question #20

Hello everyone! I am going to do question #20 (again) for those who didn't understand.

20) In a magic square, the sum of each row, column, and diagonal is the same. Copy and complete this magic square.

So first of all you find out the sum of the diagonal of the square.

And the sum is:

So now we know the sum, now we have to fill in the squares to make a sum of -2 1/2.

Next you have to do the easier ones first. The ones that have 2 squares filled in already.

You add up the two numbers and subtract it from -2 1/2

(-5/6)+(1/2)= -1/3

(-2 1/2)-(-1/3)= -2 1/6

1/2+(-1 1/6)= -2/3

-2 1/2-(-2/3)= -1 5/6

Then you do the same process again.

-1/2+(-2 1/6)= -2 2/3
-2 1/2-(-2 2/3)= 1/6

-1/2+(-1 5/6)= -2 1/3

-2 1/2-(-2 1/3)= -1/6

Now we have one more square to do. But you should always check your answer just in case.

We do the same thing, you could choose which numbers. You could go vertical or horizontal.

I'm going to do both ways to show that it doesn't really matter as long as you get the right answer.

1/6+(-1 1/6)= -1

-2 1/2-(-1)= -1 1/2

OR

-1/6+(-5/6)= -1
-2 1/2-(-1)= -1 1/2

I got the same answer so now we fill in the last square.

And that is how you do question #20!
