Question

compute.
$-3.53 + 46.78 = square$
$-72.6 + (-56.8) = square$

Explanation:

Step1: Rewrite as subtraction

$46.78 - 3.53$

Step2: Calculate the first sum

$46.78 - 3.53 = 43.25$

Step3: Rewrite as negative sum

$-(72.6 + 56.8)$

Step4: Calculate the second sum

$72.6 + 56.8 = 129.4$, so $-(72.6 + 56.8) = -129.4$

Answer:
