Step 1: pick a number step 2: double it
step 3: add 5
step 4: multiply by 50
step 5: if you've had your birthday this year ,add 1764,or,if you've not yet had your birthday this year ,add 1763
step 6: subtract the year of your birth
you should end up with a number which is a combination of the number you started with followed with your age. for example ,if you are 12 and you start with the number 27, the result should be 2712.
your task :
1. let n represent the number in step 1 and show what happens through step 6.
2. explain why the result is always the original number followed by your age. What would be the expression I would use?
