Answer :

Sure, let's solve the given expressions step-by-step together.

1. First Expression: [tex]\(43 - 21\)[/tex]

To find the solution for [tex]\(43 - 21\)[/tex]:

- Start by recognizing the numbers: 43 and 21.
- Subtract 21 from 43.

[tex]\[ 43 - 21 = 22 \][/tex]

So, the result of [tex]\(43 - 21\)[/tex] is [tex]\(22\)[/tex].

2. Second Expression: [tex]\(13 - 42\)[/tex]

Now, let's solve [tex]\(13 - 42\)[/tex]:

- Start by recognizing the numbers: 13 and 42.
- Subtract 42 from 13.

Because 42 is larger than 13, the result will be negative.

[tex]\[ 13 - 42 = -29 \][/tex]

So, the result of [tex]\(13 - 42\)[/tex] is [tex]\(-29\)[/tex].

To summarize, we solved the two expressions, and the results are:

[tex]\[ 43 - 21 = 22 \][/tex]

[tex]\[ 13 - 42 = -29 \][/tex]

Thus, the answers to the given expressions are [tex]\(22\)[/tex] and [tex]\(-29\)[/tex] respectively.
