Answer :

Sure, let's work through this problem step by step!

1. Understanding the Expression:
We start with the expression [tex]\(218 + 16\)[/tex]. This is a simple arithmetic addition problem.

2. Calculate the Sum:
Add the two numbers together:
[tex]\[
218 + 16 = 234
\][/tex]

3. Adjust the Result with ±1:
The problem mentions ±1. This means we need to consider the result with an addition and a subtraction of 1. Let's do both:

- Add 1 to the Result:
[tex]\[
234 + 1 = 235
\][/tex]

- Subtract 1 from the Result:
[tex]\[
234 - 1 = 233
\][/tex]

4. Final Results:
From our calculations, we get three potential outcomes for our expression:
- The exact sum is 234
- Adding 1 gives 235
- Subtracting 1 gives 233

So, the possible results of the expression considering the ±1 adjustment are 234, 235, and 233.
