Question

find the sum.
3.5 + (-4.5) = \square

Explanation:

Step1: Understand the operation

We need to add a positive number and a negative number. The expression is \(3.5 + (-4.5)\), which is equivalent to \(3.5 - 4.5\) because adding a negative is the same as subtracting the positive.

Step2: Perform the subtraction

Subtract 4.5 from 3.5: \(3.5 - 4.5 = -1\)

Answer:

\(-1\)
