The answers to the math problems below are what you have to print in the blank squares. Each blank square represents a single digit in the number of each correct answer to a math problem. Count the number of squares(up-to-down or left-to-right) & you will know how many digits the correct number should have.
As you can see, there are 16 rows & 16 columns; the letters(A-P) stand for the rows, & the numbers(1-16) stand for the columns. The math problems are marked by row letter first, and then column number; for example, a problem marked "A1" means you must print the digit in the number's largest column first in that blank square.
The up-to-down math problems are in the left column, & the left-to-right math problems are in the right column of the table below. You will only get math problems in arithmetic & pre-algebra; division is the only arithmetic operation that has been excluded from this puzzle.
P.S.: Remember that pre-algebra rule: "Please Excuse My Dear Aunt Sally!"
