Answer :

To solve the expression [tex]\(10.8 - 20.2 + 11 - (-38.5)\)[/tex], let's break it down step-by-step:

1. Start with the subtraction and addition:
- Begin with [tex]\(10.8 - 20.2\)[/tex]. Subtracting 20.2 from 10.8 gives [tex]\(-9.4\)[/tex].

2. Add 11:
- Next, add 11 to [tex]\(-9.4\)[/tex]. So, [tex]\(-9.4 + 11 = 1.6\)[/tex].

3. Subtract a negative number, which is equivalent to adding:
- Finally, subtract [tex]\(-38.5\)[/tex]. Subtracting a negative is the same as adding a positive, so you add 38.5:
- [tex]\(1.6 + 38.5 = 40.1\)[/tex].

Therefore, the answer to the expression [tex]\(10.8 - 20.2 + 11 - (-38.5)\)[/tex] is [tex]\(40.1\)[/tex].
