Question

compute.
-2.34 + (-6.52) =
-2.8 + 45.3 =

Explanation:

Step1: Add two negative decimals

Adding a negative number is equivalent to subtraction, so $-2.34 + (-6.52) = -(2.34 + 6.52)$
$2.34 + 6.52 = 8.86$, so $-2.34 + (-6.52) = -8.86$

Step2: Add negative and positive decimals

Rewrite as subtraction of absolute values: $-2.8 + 45.3 = 45.3 - 2.8$
$45.3 - 2.8 = 42.5$

Answer:

$-2.34 + (-6.52) = -8.86$
$-2.8 + 45.3 = 42.5$
