Question

The simplified form of $-32.4+\left(-4.5\right)$.

Short answer

The simplified form of$-32.4+\left(-4.5\right)$ is $-36.9$.

Step-by-step solution

Step 1.

The statement “$-32.4+\left(-4.5\right)$.”

Step 2. Concept.

When two negative numbers are added, their absolute value is added first and the negative sign is put in front of it.

Step 3. Calculation.

Consider the provided statement “$-32.4+\left(-4.5\right)$.”

Recall that when two negative numbers are added their absolute value is added first and a negative sign is put in front of it.

So, the given expression can be simplified as,

$-32.4+\left(-4.5\right)=-32.4-4.5$

$-32.4+\left(-4.5\right)=-\left(32.4+4.5\right)$

$-32.4+\left(-4.5\right)=-\left(36.9\right)$

$-32.4+\left(-4.5\right)=-36.9$

Hence, the simplified form of $-32.4+\left(-4.5\right)$is $-36.9$.
