# The Math Teacher Knows Everything

### Requirements: 1 die, a fanfare would be nice.

### You will find a fanfare here.

### Ask a student to roll the die, double the number and add 5. He can show the class the number, but not you.

### Ask the student to multiply this number by 5.

### Ask the student to roll the die again and add this number to the total.

### Now you can tell them the numbers they rolled.

### Example:

### N_{1} = 3

### Double: 2N_{1 }= 6

### Add 5: 2N_{1} + 5 = 11

### x5: 5(2N_{1} + 5) = 55

### Roll dice:

### N_{2} = 4

### Add 4:

### 55 + 4 = 59

### The Math Teacher Knows:

### Secretly subtracts 25 from this number:

### 59 – 25 = 34

### Da! Da! There are the two numbers rolled.
