I don't know what I am doing.
Examples:
1) a + a + a
2) 4b + 2b + 5b

If you get bit by one ant and another ant and another ant→ how many ants did bite you?

If you buy 4 balls and 2 more balls and 2 more balls again - how many balls did you buy in total?

oh I see and how would I write a answer out because we can't just give answers.

So if a question was d + 4d + 3d
Would the answer be 8?

Almost....

The answer would be 8d (which means 8*d or 8 multiplied by d)

You write the answer out as

d + 4d + 3d = 8d

Or you can do it as follows

d + 4d + 3d = 5d + 3d = 8d
