Multiplication Table Of 80
The table of 80 is the list of products you get when you multiply 80 by each whole number in turn. It is one of the easier large tables, because 80 is just $8 \times 10$, so it is the 8 times table with a zero added to every product.

What Is The Table Of 80 In Words?
Reading the table aloud builds the rhythm before the numbers stick.
One times 80 is 80
Two times 80 is 160
Three times 80 is 240
Four times 80 is 320
Five times 80 is 400
Six times 80 is 480
Seven times 80 is 560
Eight times 80 is 640
Nine times 80 is 720
Ten times 80 is 800
What Is The 80 Times Table?
The 80 times table is repeated addition of 80. Each row adds one more group of eighty, so the table answers "how much is eighty, added to itself, again and again?"
Built from the ground up, the ladder looks like this:
$80$
$80 + 80 = 160$
$80 + 80 + 80 = 240$
$80 + 80 + 80 + 80 = 320$
Multiplication is the shortcut for this stacking, which is why $80 \times 4$ and "four eighties added together" both give 320.
What Are The Multiples Of 80?
The multiples of 80 are the numbers you reach by skip-counting in eighties. The first twenty are:
80, 160, 240, 320, 400, 480, 560, 640, 720, 800, 880, 960, 1040, 1120, 1200, 1280, 1360, 1440, 1520, 1600.
Every entry in the table of 80 is a multiple of 80, and each one is also a multiple of 8, of 10, and of 4. That shared inheritance is why every product ends in zero and why the leading digits follow the 8, 16, 24 rhythm of the eights.
How To Learn The 80 Times Table (Patterns, Not Memorizing)
Bhanzu teaches the few patterns that generate a table rather than drilling its facts into recall. The table of 80 grows straight out of the eights you already know, so you can rebuild any row by reasoning instead of storing it. Seeing that structure is the number sense that algebra later builds on.
Every pattern below comes from how 80 is composed: $80 = 8 \times 10$, $80 = 4 \times 20$, and $80 = 2 \times 40$.
Pattern 1: 80n is the 8 table with a zero appended. Because $80 = 8 \times 10$, the eights (8, 16, 24, 32) become the eighties when you append a 0: 80, 160, 240, 320. The zero is the $\times 10$; the eights carry the rest. This is why fluency in the 8 times table unlocks the eighties for free.
Pattern 2: The 80s are the 40s doubled. Since $80 = 2 \times 40$, every multiple of 80 is double the matching multiple of 40. For $80 \times 6$: $40 \times 6 = 240$, doubled is 480.
Pattern 3: The 80s are the 20s times four. Because $80 = 4 \times 20$, every multiple of 80 is four times the matching multiple of 20. For $80 \times 7$: $20 \times 7 = 140$, times four is 560.
Pattern 4: Split the multiplier by place value. A large row decomposes the way the number is written. For $80 \times 13$, read 13 as $10 + 3$, so $80 \times 13 = (80 \times 10) + (80 \times 3) = 800 + 240 = 1040$ - the distributive idea you meet again as $80(10 + 3)$ in algebra.
How Do You Read And Use The Table Of 80?
Read each row left to right: $80 \times 6 = 480$ is "eighty multiplied six times gives four hundred eighty." The first number is the group size, the second is the count of groups, and the product is the total.
To learn it, recite the eights and add a zero as you go, then quiz yourself in a shuffled order so you are recalling facts rather than chanting them. A quick way to double-check a large row is mental math tricks like halving to the 40s and doubling back.
Where Does The Table Of 80 Appear And Matter In Real Life?
Eighty shows up wherever quantities move in large, round steps. An 80-count carton of eggs, an 80-character line of text, or an 80-seat coach filled several times over all scale on this table.
It also appears in percentages built on 80 marks, in money counted in eighties, and in any rate measured per 80 units - so anyone loading crates or reading a large tally is working off the eighties.
Solved Examples Of The Table Of 80
Example 1
What is $80 \times 7$?
Use the eights-plus-zero: $8 \times 7 = 56$, then add a zero.
$80 \times 7 = 560$
Final answer: $80 \times 7 = 560$.
Example 2 (Wrong path first)
A carton holds 80 eggs. How many eggs are in 9 cartons?
Wrong attempt. The rusher reads $80 \times 9$ as just $8 \times 9$ and stops at 72.
Why it breaks. Nine cartons of eighty eggs each must hold far more than a single carton, so 72 cannot be right; it is less than even one carton's 80.
Correct. Take $8 \times 9 = 72$, then add the zero that belongs to the 80.
$80 \times 9 = 720$
Final answer: 720 eggs.
Example 3
Find $80 \times 12$.
Split it: $80 \times 10 = 800$ and $80 \times 2 = 160$.
$800 + 160 = 960$
Final answer: $80 \times 12 = 960$.
Example 4
$80 \times {?} = 400$.
Divide to find the missing factor: $400 \div 80 = 5$.
Final answer: $80 \times 5 = 400$.
Example 5
A conveyor moves 80 boxes a minute. How many boxes in 15 minutes?
$80 \times 15 = (80 \times 10) + (80 \times 5) = 800 + 400 = 1200$.
Final answer: 1200 boxes.
What Are Common Mistakes With The Table Of 80?
Mistake 1: Dropping the zero from the 8-table pattern
Where it slips in: Using the eights-plus-zero method but forgetting to append the zero.
Don't do this: Writing $80 \times 6 = 48$ (the bare $8 \times 6$, no zero).
The correct way: Take $8 \times 6 = 48$, then add one zero, giving $80 \times 6 = 480$.
Mistake 2: Confusing the table of 80 with the table of 8
Where it slips in: Under time pressure, the first instinct is to answer $80 \times 8$ with the $8 \times 8 = 64$ fact and stop there.
Don't do this: Answering $80 \times 8 = 64$.
The correct way: $80 \times 8 = 640$. The 64 is right; the missing zero is the place value that turns it into the table of 80.

Conclusion
The table of 80 is the 8 times table wearing a zero, so once the eights are fluent, the eighties come almost for free through place value. Keep the doubling route from the 40s and the split-by-place-value route as backups for the larger rows.
To build this pattern-first habit with guidance, a structured mental maths for kids program starts early, and speed math classes turn round-table fluency into fast, reliable mental arithmetic.
