Sure, Hanna Nicol! Let's go through the steps to find the sums of the given expressions in detail.
### 1. Calculate [tex]\((-3) - (+1)\)[/tex]
To solve [tex]\((-3) - (+1)\)[/tex]:
1. Begin with [tex]\(-3\)[/tex].
2. Subtract [tex]\(+1\)[/tex] from [tex]\(-3\)[/tex]:
Adjusting the expression,
[tex]\[
(-3) - (+1) = -3 - 1
\][/tex]
3. Subtracting 1 from [tex]\(-3\)[/tex]:
[tex]\[
-3 - 1 = -4
\][/tex]
So,
[tex]\[
(-3) - (+1) = -4
\][/tex]
### 2. Calculate [tex]\(+2\)[/tex]
To solve [tex]\(+2\)[/tex]:
1. Simply consider [tex]\(+2\)[/tex] as it is.
2. There is no additional operation required.
So,
[tex]\[
+2 = 2
\][/tex]
### 3. Calculate [tex]\((-4) + (+5)\)[/tex]
To solve [tex]\((-4) + (+5)\)[/tex]:
1. Begin with [tex]\(-4\)[/tex].
2. Add [tex]\(+5\)[/tex] to [tex]\(-4\)[/tex]:
Adjusting the expression,
[tex]\[
(-4) + (+5) = -4 + 5
\][/tex]
3. Adding [tex]\(5\)[/tex] to [tex]\(-4\)[/tex]:
[tex]\[
-4 + 5 = 1
\][/tex]
So,
[tex]\[
(-4) + (+5) = 1
\][/tex]
### Summary
- The sum of [tex]\((-3) - (+1)\)[/tex] is [tex]\(-4\)[/tex].
- The value of [tex]\(+2\)[/tex] is [tex]\(2\)[/tex].
- The sum of [tex]\((-4) + (+5)\)[/tex] is [tex]\(1\)[/tex].
So, the solutions are:
[tex]\[
(-3) - (+1) = -4
\][/tex]
[tex]\[
+2 = 2
\][/tex]
[tex]\[
(-4) + (+5) = 1
\][/tex]
