One possible expression that has both addition and subtraction to simplify a positive number using the given numbers is:
4.3 + (-1.07) - (-2.971)
Reasoning:
- The first number, 4.3, is positive, so it contributes to making the expression positive.
- The second number, -1.07, is negative, so it subtracts from the positive value of the expression.
- The third number, -2.971, is also negative, but since it is subtracted (i.e., preceded by a minus sign), it effectively becomes positive in the expression and adds to its value.
By combining all three numbers in the expression, we have a combination of addition and subtraction that ultimately results in a positive number.
Using the numbers 4.3, -1.07, and -2.971, write on expression that has BOTH ADDITION AND SUBTRACTION to simply a POSTIVE number. (WITH REASONING)
