Alright, let's go through each problem step by step:

a) Calculate [tex]\(800 + 100\)[/tex]:

First, add the hundreds place:
[tex]\[ 800 + 100 = 900 \][/tex]

So, [tex]\(800 + 100 = 900\)[/tex].

b) Calculate [tex]\(500 + 20\)[/tex]:

First, add the tens place:
[tex]\[ 500 + 20 = 520 \][/tex]

So, [tex]\(500 + 20 = 520\)[/tex].

c) Calculate [tex]\(1005 + 5\)[/tex]:

First, add the units place:
[tex]\[ 1005 + 5 = 1010 \][/tex]

So, [tex]\(1005 + 5 = 1010\)[/tex].

d) Calculate [tex]\(200 + 1000\)[/tex]:

First, add the hundreds place:
[tex]\[ 200 + 1000 = 1200 \][/tex]

So, [tex]\(200 + 1000 = 1200\)[/tex].

e) Calculate [tex]\(70 + 50\)[/tex]:

First, add the tens place:
[tex]\[ 70 + 50 = 120 \][/tex]

So, [tex]\(70 + 50 = 120\)[/tex].

i) Calculate [tex]\(60000 + 10000\)[/tex]:

First, add the thousands place:
[tex]\[ 60000 + 10000 = 70000 \][/tex]

So, [tex]\(60000 + 10000 = 70000\)[/tex].

These are the results for each calculation:

a) [tex]\(800 + 100 = 900\)[/tex]

b) [tex]\(500 + 20 = 520\)[/tex]

c) [tex]\(1005 + 5 = 1010\)[/tex]

d) [tex]\(200 + 1000 = 1200\)[/tex]

e) [tex]\(70 + 50 = 120\)[/tex]

i) [tex]\(60000 + 10000 = 70000\)[/tex]
