Answer 3

Examples using the multiplication sign:

1. 3 + 3 + 3 + 3 + 3 + 3 = 3 * □ = □ - In this example, we have six instances of the number 3 being added together. We can rewrite this using the multiplication sign as 3 * 6 = 18.

2. 2 + 2 + 2 + 2 + 2 + 2 = 2 * □ = □ - Here, we have six instances of the number 2 being added together. Using the multiplication sign, we can express this as 2 * 6 = 12.

3. 4 + 4 + 4 = 4 * □ = □ - In this case, we have three instances of the number 4 being added together. Using the multiplication sign, we can write this as 4 * 3 = 12.

4. 5 + 5 + 5 = □ * □ = □ - Here, we have three instances of the number 5 being added together. We can express this using the multiplication sign as 5 * 3 = 15.

5. 7 + 7 = □ * □ = □ - In this example, we have two instances of the number 7 being added together. Using the multiplication sign, we can write this as 7 * 2 = 14.

Please note that the values of the missing variables (□) cannot be determined without additional information. The examples provided demonstrate how the addition expressions can be rewritten using the multiplication sign.
