Answer 2

Step-by-step explanation:

After dinner, say, turn the conversation towards numbers and bring out your business card. Explain the basic idea behind a magic square; that every column and row adds up to the same number. Let your companions verify this if they wish by adding the columns and rows.

Tell them you’ll try and make a magic square just for them. Ask them to give you any two-digit number higher than 34.

Let’s assume they give you the number 87. Leave your business card where you can see it and bring out another piece of paper. Draw a 4×4 grid. From the target number that your guests named, subtract the number 34. In our example 87 is the target number: 87 minus 34 = 53. You then divide 53 by 4, to the nearest whole number. That gives 13 with a remainder of 1 (13 x 4 = 52; 52 + 1 = 53).

Remember the number 13. We call that the quotient, and it’s one of two special numbers you’ll need. The other special number is the quotient plus the remainder. In our case, that’s 14 (13 + 1).

Now you’re set. Begin by stealing a glance at your business card. Look at the top row. Add your first special number to the 8 that appears in row 1, column 1 of your card: 13 + 8 = 21. Write this down in the corresponding box on your new grid.

You will continue on like this for all 16 spaces in the grid, with four exceptions. When you get to the numbers 13, 14, 15 or 16 on your original card, you have to add the special number plus the remainder.
