Alexa will be your magician for today. She will ask you to think of a number and you just have to keep it a secret till the end.
Alexa will then ask you to think of a series of events and you have to do calculations according to those events.
You can say Done or Continue once you are finished to continue. You can say Repeat or Once More, at any time repeat previous step. You can say From Scratch or From Beginning to start from begining.
Instruction List:
[1] done/proceed/ok - to have Alexa say the next step [2] repeat - to have Alexa repeat the last step [3] from start - to have Alexa repeat from the beginning
You'll require pen and paper if you pan to choose big numbers. Enjoy !!
