Answer :

Sure, let's walk through each part of the question step-by-step and correct any errors:

### Part a)
The first problem involves an addition operation:

[tex]\[ 4 + 3 + 2 \][/tex]

Step 1: Add the first two numbers:
[tex]\[ 4 + 3 = 7 \][/tex]

Step 2: Add the result to the next number:
[tex]\[ 7 + 2 = 9 \][/tex]

So, the correct result for part (a) is:
[tex]\[ 4 + 3 + 2 = 9 \][/tex]

### Part b)
The second problem involves a subtraction operation:

[tex]\[ 37 - 13 \][/tex]

Step 1: Subtract the second number from the first number:
[tex]\[ 37 - 13 = 24 \][/tex]

So, the correct result for part (b) is:
[tex]\[ 37 - 13 = 24 \][/tex]

### Part c)
The third problem involves an addition operation:

[tex]\[ 22 + 43 \][/tex]

Step 1: Add the two numbers directly:
[tex]\[ 22 + 43 = 65 \][/tex]

So, the correct result for part (c) is:
[tex]\[ 22 + 43 = 65 \][/tex]

Putting it all together, the corrected answers are:
a) [tex]\( 4 + 3 + 2 = 9 \)[/tex]
b) [tex]\( 37 - 13 = 24 \)[/tex]
c) [tex]\( 22 + 43 = 65 \)[/tex]
