1. 10^15 Floating Point Operations Per Second

2. Multiply the number of feet by 12.

3. 2.5 * 12 = 30 inches

4. Multiply the number of nanoseconds by 1,000

5. 2.5 * 1000 = 2,500 picoseconds

6. 1/(4 * 10^9) = 0.250 * 10^-9 seconds
                = 0.250 nanoseconds
                = 250.0 picoseconds

7. 1/(2.5 * 10^-3) = 0.400 * 10^3 Hertz
                   = 0.400 KHz
                   = 400.0 Hz

8. 1/(44.0 *10^3)  = 0.227000 * 10^-3 seconds
                   = 227.0000 milliseconds
                   = 227000.0 microseconds

9. ceil(log2(7)) = 3
