-5.27 + (-3.32) = ? -6.8 + 19.5 = ?

Understand the Problem

The question involves performing addition with negative and positive numbers. We need to calculate the sums of the given expressions to arrive at the final answers.

Answer

- First expression: $-8.59$ - Second expression: $12.7$

Steps to Solve

Calculate the First Expression

To solve $-5.27 + (-3.32)$, we add the two negative numbers. Since both numbers are negative, we simply add their absolute values:

$$ |-5.27| + |-3.32| = 5.27 + 3.32 = 8.59 $$

Then we apply the negative sign to the result:

$$ -5.27 + (-3.32) = -8.59 $$

Calculate the Second Expression

Now let's solve $-6.8 + 19.5$. In this case, we have a negative number and a positive number.

First, since $19.5$ is larger than $6.8$, we subtract $6.8$ from $19.5$:

$$ 19.5 - 6.8 = 12.7 $$

Then the result is positive:

$$ -6.8 + 19.5 = 12.7 $$

The first answer is $-8.59$.
The second answer is $12.7$.

More Information

The first expression combines two negative values, resulting in a more negative sum. The second expression combines a negative and a positive value, leading to a positive outcome. This shows the importance of understanding how to work with positive and negative signs in addition.

Tips

Misunderstanding the addition of negative numbers by thinking they will result in a positive sum.
Confusing the operation when combining a negative and a positive number; remember to always subtract the smaller from the larger and keep the sign of the larger number.
