What's my number?
I’m thinking of a number.
I get the same answer if I add 8 to my number, or if I don’t
add 8 but instead I triple my number.
What number am I thinking of?
1. What does tripling a number do to it? Think about a number, triple it,
then think about what happened to that original number?
2. When you triple a number, it is the same as adding in up ...how many
times?
3. What does adding 8 do to a number? How much bigger will it get?
4. If adding 8 gives the same answer as tripling it, what can you say about
that number?
