🔍 Key Concepts

• SI prefixes for large numbers (kilo, mega, giga, tera, etc.) • The pattern of powers of 10 between these prefixes • Every step up in these prefixes usually changes by a factor of 1,000 (10^3)

💭 Think About

• Think about the order of familiar data sizes: kilobyte, megabyte, gigabyte, terabyte. Which one comes first, second, third, and fourth? • If kilo is 10^3 and mega is 10^6, what power of 10 is added each time you go up one step? • Compare 'giga' and 'tera' in terms of how many times larger tera is than giga.

✅ Before You Answer

• Recall the correct powers for kilo (k), mega (M), and giga (G) before deciding tera (T). • Confirm that each step increases the exponent on 10 by 3 (i.e., 10^3 more each time). • Make sure you match the correct power of 10 to the English word: thousand, million, billion, or trillion.
