Final answer:

To find 3−(−5), rewrite it as 3 + 5 which equals 8, since subtracting a negative number is equivalent to addition.

Step-by-step explanation:

To find 3−(−5) using the Missing-Addend Approach, we start by acknowledging the subtraction of a negative number is the same as addition. We can rewrite the equation as 3 + 5 because subtracting a negative is the same as adding a positive. Now, we simply perform the addition of two positive numbers.

When two positive numbers are added, the answer has a positive sign. So, 3 + 5 equals 8.

The final answer to 3−(−5) is therefore 8.
