A man was 10 meters underwater. After 10 minutes he goes another 13 meters down. How deep is he?

-10 + -13 = -23. i just add another 10 then a 3

A man was in debt of £300. Over the year he paid £500. In return he got £200 to spend for him and his family. He spent all of it and yet again had bills for £250. He paid over the year £225 of it and paid the rest the next month. He had another final bill of £900. He paid £1000 and got £100 to spend on him and his family.He spent all of it again on his family and himself. He got bankrupt and paid the other bills. THE END.

-300 + 500 - 200 - 250 + 225 + 25 -900 + 1000 - 100 = 0 All you do is use ure mind and add and subtract.
