# Worksheet: Orders of Magnitude

In this worksheet, we will practice expressing measurements in scientific notation to determine the orders of magnitude of values found from calculations.

**Q2: **

Determine how many floating-point operations a supercomputer can perform in a human lifetime. Use a value of s as the time for a single floating-point operation in a supercomputer and a value of s for a human lifetime.

- A floating-point operations per human lifetime
- B floating-point operations per human lifetime
- C floating-point operations per human lifetime
- D floating-point operations per human lifetime
- E floating-point operations per human lifetime

**Q17: **
