Answer: The answers are:
6 + 2 = 8
4 + (-1) = 3
Explanation:
Add 6 by 2.
Solve for X.
4 + X = 3
To find X, we use the integer rule. We can use this:
Positive and Positive = Positive
Negative and Negative = Negative
Positive and Negative = Both (It depends if the negative or positive is larger than the other)
For this problem, we can use: Positive and Negative = Both.
If we look at the chart, we can see 4 and 3. How can we get 4 + ? = 3? We can use the integer, -1. Since we said, Positive and Negative = Both, we must compare the positive-addend (4) by the negative-addend (-1).
4 is greater than -1
4 > -1
Therefore, X equals -1.
4 + (-1) = 3
