Using the numbers 4.3, -1.07, and -2.971, write on expression that has addition and subtraction to simply a postivie number. (WITH REASONING)

Answer 1

To obtain a positive number, we can add all three numbers together since two of them are already negative and adding a positive number to negative numbers results in a smaller negative number.

Expression: 4.3 + (-1.07) + (-2.971)

Reasoning: When we add 4.3 (a positive number) to -1.07 and -2.971 (both negative numbers), the positive number will counterbalance the negativity, resulting in a positive sum.
