Rick's Approach:
Rick is subtracting a negative number from -6. According to the rules of subtraction, subtracting a negative number is equivalent to adding its positive counterpart. So, -6 - (-2) becomes -6 + 2, which equals -4.
Michael's Approach:
Michael seems to be interpreting -6 - (-2) as a straightforward subtraction. When we subtract a negative number, it's like adding its positive counterpart. Thus, -6 - (-2) is the same as -6 + 2, which also equals -4.
Both Rick and Michael arrived at the correct result of -4 for the expression -6 - (-2). They applied the correct principles of subtraction, considering that subtracting a negative number is the same as adding its positive counterpart. Therefore, both approaches are correct, and the result is the same in either case.
