Explain how to find the sum using game chips, then give the answer 8+-10
To find the sum using game chips, you can represent positive numbers with one color of chips, and negative numbers with a different color. In this case, let's say you use red chips for positive numbers and blue chips for negative numbers.
To find the sum of 8 + (-10), you would need 8 red chips to represent the positive 8, and 10 blue chips to represent the negative 10.
Start by placing the 8 red chips in front of you. Then take 10 blue chips and arrange them in a separate pile. Now, to represent subtraction, you can imagine removing blue chips from the pile.
To subtract 10 blue chips from the pile, start by picking up one blue chip and setting it aside. Repeat this process nine more times until you have subtracted a total of ten blue chips.
Next, observe the number of chips you have remaining. If you have more red chips than blue chips left, it means the sum is positive. If you have more blue chips than red chips, it means the sum is negative.
In this case, you will have 8 red chips remaining and no blue chips left. Since you have more red chips than blue chips, the sum is positive.
Therefore, the sum 8 + (-10) equals -2.
By using game chips, you can physically represent positive and negative numbers to visualize the addition or subtraction operation.
