Here are the completed calculations: 1. Complete the following: a) 4 - 4 = 0 Step 1: To make the equation true, the number subtracted from 4 must be 4. 4 - 4 = 0 The completed value is 4. b) 20 - 15 = 5 Step 1: Choose a number for the first box, for example, 20. Step 2: Calculate the result. 20 - 15 = 5 The completed values are 20 and 5. (Other valid pairs are possible, e.g., 15 and 0, or 30 and 15). c) 100000 - 50000 = 50000 Step 1: Choose a number to subtract from 100,000, for example, 50,000. Step 2: Calculate the result. 100000 - 50000 = 50000 The completed values are 50000 and 50000. (Other valid pairs are possible). d) 299999 - 299999 = 0 Step 1: To make the equation true, the number from which 299,999 is subtracted must be 299,999. 299999 - 299999 = 0 The completed value is 299999. e) 100 - 50 = 50 Step 1: Choose two numbers for the first two boxes, for example, 100 and 50. Step 2: Calculate the result. 100 - 50 = 50 The completed values are 100, 50, and 50. (Other valid triplets are possible). 2. Replace: The values for the shapes are: • Red square = 5 • Green rectangle = 25 • Red hexagon = 0.5 • Yellow circle = 500 • Blue pentagon = 0 (based on the blurry image and context) a) Yellow circle - Yellow circle = 0 Step 1: Replace the shapes with their values. 500 - 500 = 0 The calculation is 500 - 500 = 0. b) Red square - Red square = 0 Step 1: Replace the shapes with their values. 5 - 5 = 0 The calculation is 5 - 5 = 0. c) Red hexagon - Red hexagon = 0 Step 1: Replace the shapes with their values. 0.5 - 0.5 = 0 The calculation is 0.5 - 0.5 = 0. d) Blue pentagon - Blue pentagon = 0 Step 1: Replace the shapes with their values (assuming Blue pentagon = 0). 0 - 0 = 0 The calculation is 0 - 0 = 0. e) Green rectangle - Green rectangle = 0 Step 1: Replace the shapes with their values. 25 - 25 = 0 The calculation is 25 - 25 = 0.
