Multiplication Table Of 400
The table of 400 is the list of products you get when you multiply 400 by each whole number in turn. It is one of the easiest large tables, because $400 = 4 \times 100$, so it is the 4 times table with two zeros added to every product.

What Is The Table Of 400 In Words?
Reading the table aloud builds the rhythm before the numbers stick.
One times 400 is 400
Two times 400 is 800
Three times 400 is 1200
Four times 400 is 1600
Five times 400 is 2000
Six times 400 is 2400
Seven times 400 is 2800
Eight times 400 is 3200
Nine times 400 is 3600
Ten times 400 is 4000
What Is The 400 Times Table?
The 400 times table is repeated addition of 400. Each row adds one more group of four hundred, so the table answers "how much is four hundred, added to itself, again and again?"
Built from the ground up, the ladder looks like this:
$400$
$400 + 400 = 800$
$400 + 400 + 400 = 1200$
$400 + 400 + 400 + 400 = 1600$
Multiplication is the shortcut for this stacking, which is why $400 \times 4$ and "four four-hundreds added together" both give 1600.
What Are The Multiples Of 400?
The multiples of 400 are the numbers you reach by skip-counting in four-hundreds. What are the multiples of 400? The first twenty are:
400, 800, 1200, 1600, 2000, 2400, 2800, 3200, 3600, 4000, 4400, 4800, 5200, 5600, 6000, 6400, 6800, 7200, 7600, 8000.
Every entry in the table of 400 is a multiple of 400, and every one is also a multiple of 4, of 100, and of 200. That shared inheritance is why each product ends in two zeros and why the digits before them follow the 4, 8, 12, 16 rhythm of the fours.
How To Learn The 400 Times Table (Patterns, Not Memorizing)
Bhanzu teaches the few patterns that generate a table rather than drilling its facts into recall. The table of 400 grows straight out of the fours you already know, so you can rebuild any row by reasoning instead of reciting it.
Every pattern below comes from how 400 is composed: $400 = 4 \times 100$ and $400 = 20 \times 20$.
Pattern 1: 400n is the 4 table with two zeros appended. Because $400 = 4 \times 100$, the fours (4, 8, 12, 16) become the four-hundreds when you append two zeros: 400, 800, 1200, 1600. The two zeros are the $\times 100$; the 4 times table carries the rest.
Pattern 2: 400 is 20 squared. Because $400 = 20 \times 20$, every multiple of 400 is twenty times the matching multiple of 20, which is also why 400 turns up as a perfect square. If you know the 20 times table, $20 \times 6 = 120$, then twenty of those is 2400.
Pattern 3: Use the 40s, then add a zero. Since $400 = 40 \times 10$, you can take a value from the forties and append one zero. For $400 \times 7$: $40 \times 7 = 280$, then a zero gives 2800.
Pattern 4: Only the front digits change. Every product ends in 00, so the multiplication really happens on the fours; the two zeros just ride along. If a row does not end in 00, the answer is wrong before you check anything else.
How Do You Read And Use The Table Of 400?
Read each row left to right: $400 \times 6 = 2400$ is "four hundred multiplied six times gives two thousand four hundred." 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 fours and add two zeros as you go, then quiz yourself in a shuffled order so you are recalling facts rather than chanting a list. The 4-table-plus-zeros link is your safety net, so if a row slips, rebuild it from the fours you already know.
Where Does The Table Of 400 Appear?
Four hundred is the math of tracks and squares. One lap of a standard athletics track is 400 metres, so the table of 400 counts total distance across several laps, and the 400-metre dash is a race named for exactly one of them.
Because $400 = 20 \times 20$, it is also the area of a 20-by-20 square in square units, which makes it a common answer in geometry. It shows up wherever a round 400 repeats: 400 grams per pack across a case, or 400 seats per section in a stadium.
Anyone counting laps or squaring a 20 is reading off this table.
Solved Examples Of The Table Of 400
Example 1
What is $400 \times 6$?
Use the fours-plus-two-zeros route.
$4 \times 6 = 24$
Append two zeros.
$400 \times 6 = 2400$
Final answer: $400 \times 6 = 2400$.
Example 2 (Wrong path first)
A warehouse stores 400 boxes per aisle. How many boxes are in 8 aisles?
Wrong attempt. The rusher reads $400 \times 8$ as just $4 \times 8$ and writes 32.
Why it breaks. Eight aisles of four hundred boxes must hold thousands, so 32 cannot be right; it is smaller than a single box count.
Correct. Take $4 \times 8 = 32$, then append the two zeros that belong to the 400.
$400 \times 8 = 3200$
Final answer: 3200 boxes.
Example 3
Find $400 \times 12$.
Split the multiplier: $400 \times 10 = 4000$ and $400 \times 2 = 800$.
$4000 + 800 = 4800$
Final answer: $400 \times 12 = 4800$.
Example 4
$400 \times {?} = 4400$.
Divide to find the missing factor: $4400 \div 400 = 11$.
Final answer: $400 \times 11 = 4400$.
Example 5
A runner completes 5 laps of a 400-metre track. How far is that?
Use the fours-plus-zeros route: $4 \times 5 = 20$, then two zeros.
$400 \times 5 = 2000$
Final answer: 2000 metres.
What Are Common Mistakes With The Table Of 400?
Mistake 1: Dropping a zero from the 4-table pattern
Where it slips in: Using the fours-plus-two-zeros method but appending only one zero.
Don't do this: Writing $400 \times 6 = 240$ (only one zero added).
The correct way: Take $4 \times 6 = 24$, then add two zeros, giving $400 \times 6 = 2400$.
Mistake 2: Confusing the table of 400 with the table of 4
Where it slips in: Under time pressure, the first instinct is to answer $400 \times 8$ with the $4 \times 8 = 32$ fact and stop there.
Don't do this: Answering $400 \times 8 = 32$.
The correct way: $400 \times 8 = 3200$. The 32 is right; the two missing zeros are the place value that turns it into the table of 400, and checking that the answer ends in 00 catches this at a glance.

$400 \times 20 = {?}$
A runner does 7 laps of a 400-metre track. How far is that?
Answers: 1. 1600 2. 3600 3. 12 4. 2400 5. 4400 6. $400 \times 7 = 2800$ is larger 7. 8000 8. 2800 metres.
Conclusion
The table of 400 is not a wall of facts to store; it is the 4 table with two zeros on the end, so any row rebuilds from the fours or from the $20 \times 20$ square. Learn the four patterns and a missing zero becomes an obvious flag rather than a silent error.
To take this further with a teacher, explore speed math classes or an elementary math tutor who can build the same reasoning across every table.
