-6 +(-3) and -6 + 3 (are or not equivalent

Answer 1

To determine if the expressions $-6+(-3)$ and $-6+3$ are equivalent, let's evaluate each expression:

1. $-6+(-3)$: $$-6+(-3)=-6-3=-9$$

2. $-6+3$: $$-6+3=-3$$

Now, we can compare the results:

• The first expression evaluates to $-9$.
• The second expression evaluates to $-3$.

Since $-9$ is not equal to $-3$, the two expressions are not equivalent.
