Answer
When \( z = -6 \), the expression \( z + 3 \) equals -3.
Solution
Substitute \( z=-6 \) into the expression \( z+3 \).
Evaluate the expression by following steps:
- step0: Evaluate:
\(z+3\)
- step1: Substitute:
\(-6+3\)
- step2: Add the numbers:
\(-3\)
The value of the expression \( z+3 \) when \( z=-6 \) is -3.

To evaluate the expression \( z + 3 \) for \( z = -6 \), simply substitute \(-6\) for \(z\) in the equation. So, that means: \[ -6 + 3 = -3 \] And voilà! The answer is \(-3\). Now, isn't it interesting how simple arithmetic like this plays a crucial role in everything from budgeting to engineering? Just think of all the calculations that go on behind the scenes in building bridges, programming apps, or even trying to cook a perfect meal by adjusting ingredient ratios!
