How do I set a force number? 

You can set a force number from the Solo: Preferences section of the NKTW app. Type in the full force number and hit set - the digits will turn green to let you know its worked. A force number is the number the calculator will force upon the spectator as the (fake) answer to the large sum. 

What is a prediction time? 

The prediction time is the time that gets sent to the watch - it will match the spectators random time. 

How to trigger the force number and prediction time? 

Is calculator mode not sending a time to the watch? Maybe calculator mode isn't working for you. A common reason is that users simply are not using a long enough sum to trigger the magic. 

We chose a specific length of sum so that the spectator can test the calculator with random sums before you begin the trick. 

You must use a sum with three multiplication to trigger the prediction time and the force number. For example: 

1 x 2 x 3 x 4 = MAGIC 

For clarity, a sum with three multiplications includes four numbers and three multiplications. Sometimes users only type in three numbers and only two multiplications. So long as you use a sum with three multiplications, the magic will automatically trigger. 

How do I peek the prediction time from calculator mode?

How do I resend the time to the watch from calculator mode? 

This is easy, simple tap the equals (=) button again. Every time you tap the equals button the most recent prediction time is resent to the watch. 

How do I reset the watch in calculator mode?
