Activity 3. MATH PUZZLE BOXES: Each puzzle contains the numbers 1- 9. Each column and each row add up to the number given outside the boxes. Put the correct number in each box to complete the addition equations without repeating any numbers. 4 15 2 15 5 11 5 20 4 1 10 9 20 3 1 10 8 6 1 14 14 8 23 20 13 12 18 14 13 3 16 5 15 8 17 7 3 13 16 1 15 8 16 9 14 4 13 12 16 17 12 20 13 19 7 19 2 15 8 13 16 4 14 2 15 6 1 11 6 16 5 17 9 18 14 16 15 15 19 11 16 13 16

Logic: Cross Math Puzzles - Fill in the empty cross math puzzle, each row and column must be filled with numbers from 1 to 9 to complete each equation. Each box may only be used once in the puzzle. The orders of operations apply. Each digit from 1 to 9 must be used exactly once in each row and column. Cross Math #1 Cross Math #2 Cross Math #3 Cross Math #4

Instructions: Try to fill in the missing numbers. Use the numbers 1 through 9 to complete the equations. Each number is only used once. Each row is a math equation. Each column is a math equation. Remember that multiplication and division are performed before addition and subtraction
Jerelyn N.
Using the integers 1 to 9 at most one time each, fill in the boxes twice __ __ +x = __ __: once to make a positive solution and once to make a negative solution. You may reuse all the digits for each solution. Your solutions should be displayed both numerically and graphically.
