Zillion Isn’t a Real Number

 

⭐ What Comes After “Zillion”?

Understanding Real & Made‑Up Big Number Names

When someone says they have “a zillion things to do,” you already know they don’t literally mean a number. But it feels like a number, right? So what actually comes after zillion? And is zillion even real?

Let’s break it down in a fun, simple way.

🧠 First Things First: “Zillion” Isn’t a Real Number

Words like zillion, gazillion, and bazillion are slang. They’re playful, exaggerated ways to say:

“A huge amount... so big I don’t want to count it!”

Because zillion isn’t part of the official number system, there is no mathematically correct “next number.” It’s not 10⁶, 10⁹, or anything measurable. It’s just a fun word.

So technically, nothing comes after zillion, because zillion isn’t part of the real sequence.

📏 The Real Big Number Sequence

If you want to know what comes after the largest real numbers we use, here’s the official list in the short scale (used in the U.S.):

• Million — 10⁶

• Billion — 10⁹

• Trillion — 10¹²

• Quadrillion — 10¹⁵

• Quintillion — 10¹⁸

• Sextillion — 10²¹

• Septillion — 10²⁴

• Octillion — 10²⁷

• Nonillion — 10³⁰

• Decillion — 10³³

And it keeps going…

All the way up to centillion, which is 10³⁰³, a number with 303 zeros!

These names follow a pattern based on Latin roots, so technically you can keep going forever.

😂 What About “Gazillion,” “Bazillion,” and “Kajillion”?

These are made‑up words, just like zillion. They don’t have official values. They’re used for humor, exaggeration, or storytelling.

Kids love them. Adults use them when they’re overwhelmed. Mathematicians ignore them completely.

🧩 So What Does Come After Zillion?

If you’re talking real math, the next number after the biggest official “‑illion” is simply the next “‑illion” in the Latin sequence.

If you’re talking slang, people often say:

• Gazillion

• Bazillion

• Kajillion

• Squillion (popular in the UK)

But again, none of these are real numbers.

🌟 Why This Matters (Especially for Kids Learning Math)

Understanding the difference between real numbers and fun, exaggerated words helps kids:

• Build strong number sense

• Recognize patterns in large-number naming

• Understand that math has structure, but language can be playful

It’s a great conversation starter in classrooms, homeschool lessons, or educational blogs.

📝 Final Takeaway

Zillion isn’t a real number, so nothing officially comes after it. But the real number system keeps going far beyond the ones we use every day... all the way to centillion and beyond.

And if you want to be silly? Sure, you can say gazillion comes next.

Math won’t mind.

⭐ Big Number Adventure: Real vs. Silly Numbers ACTIVITY

A Fun Activity to Go With “What Comes After Zillion?”

🎯 Objective

Students will learn the difference between real large-number names and made‑up exaggeration words like zillion, gazillion, and bazillion.

🧩 Activity: Sort the Numbers!

Print or display the cards below. Students sort them into two categories:

Category 1: Real Numbers

• Million

• Billion

• Trillion

• Quadrillion

• Quintillion

• Sextillion

• Septillion

• Octillion

• Nonillion

• Decillion

Category 2: Silly / Made‑Up Numbers

• Zillion

• Gazillion

• Bazillion

• Kajillion

• Squillion

📝 Student Directions

1. Cut out the number cards.

2. Sort them into Real Numbers and Silly Numbers.

3. Glue them onto a sorting mat or place them in the correct column.

4. Choose one real number and write what it equals (example: Trillion = 1,000,000,000,000).

5. Choose one silly number and write a funny sentence using it.

✏️ Extension: Create Your Own “‑illion” Word!

Students invent a new number name using Latin roots or pure imagination.

Examples:

• Funillion

• Snackillion

• Puppillion

Then they complete:

• My number name is: __________

• It means: __________________________________

• Draw what this number might look like!

🎉 Optional Challenge (Grades 3–6)

Match each real number to its power of ten:

• Million → 10⁶

• Billion → 10⁹

• Trillion → 10¹²

• Quadrillion → 10¹⁵

• Quintillion → 10¹⁸

You can expand this list depending on the grade level.

🧠 Teacher / Parent Notes

This activity helps students:

• Understand number naming patterns
