Describe this as a 7th grader and simplify it alot so it can be small but still have some info

Answer 1

Sure! To add 10.82 and -15.96, you can think of it like this:

1. Since you have a positive number (10.82) and a negative number (-15.96), you can actually subtract the smaller number from the larger one.

2. First, find the difference: \( 15.96 - 10.82 = 5.14 \).

3. Since -15.96 is more negative, the result will also be negative. So, you write it as \(-5.14\).

So, \( 10.82 + (-15.96) = -5.14 \).
