Here are the solutions for the addition and subtraction problems. First Table: Column 1: 20 + 3 + 5 = 28 Column 2: 27 + (-2) + 3 = 27 - 2 + 3 = 25 + 3 = 28 Column 3: 32 + (-2) + 5 = 32 - 2 + 5 = 30 + 5 = 35 Column 4: 26 + (-1) + 2 = 26 - 1 + 2 = 25 + 2 = 27 Column 5: 34 + (-2) + 1 = 34 - 2 + 1 = 32 + 1 = 33 Column 6: 25 + 3 + (-5) = 25 + 3 - 5 = 28 - 5 = 23 Column 7: 38 + 1 + (-4) = 38 + 1 - 4 = 39 - 4 = 35 Second Table: Column 1: 39 + (-4) + 2 = 39 - 4 + 2 = 35 + 2 = 37 Column 2: 22 + 1 + (-2) = 22 + 1 - 2 = 23 - 2 = 21 Column 3: 37 + (-5) + (-1) = 37 - 5 - 1 = 32 - 1 = 31 Column 4: 24 + (-3) + 5 = 24 - 3 + 5 = 21 + 5 = 26 Column 5: 35 + (-5) + 4 = 35 - 5 + 4 = 30 + 4 = 34 Column 6: 23 + 1 + (-4) = 23 + 1 - 4 = 24 - 4 = 20 Column 7: 36 + (-1) + (-5) = 36 - 1 - 5 = 35 - 5 = 30
