Firstly, I read the question twice.It said, 'Baby Ben is turning one. His parents are planning to celebrate his first birthday with a special cake which will have one candle on it.They think about future birthdays too, when they will need more and more candles.They are curious to know how many candles they will need to buy for his birthday cakes, up to and including his eleventh birthday...'
Then I thought about what it was asking me to do. Secondly, I calculated the answer. I came to a conclusion of 66 for the first question. I figured this out by adding one, two, three, four, five, six, seven, eight, nine, ten and eleven all together (1+2+3+4+5+6+7+8+9+10+11=66). Therefore, baby Ben will need 66 candles.
I double checked by using the inverse and reading the question over lots of times then I finally agreed that I was correct.
Then I went to the next question and used some of the same methods again and that is how I found my answer.
