Multiplication Table Of 42
The table of 42 is the list of products you get when you multiply 42 by each whole number in turn. It is friendlier than it looks, because $42 = 6 \times 7$, so any row is just a 6-table or 7-table fact stretched by the other factor.

What Is The Table Of 42 In Words?
Reading the table aloud sets the +42 rhythm before the digits stick.
One times 42 is 42
Two times 42 is 84
Three times 42 is 126
Four times 42 is 168
Five times 42 is 210
Six times 42 is 252
Seven times 42 is 294
Eight times 42 is 336
Nine times 42 is 378
Ten times 42 is 420
What Is The 42 Times Table?
The 42 times table is repeated addition of 42. Each row adds one more forty-two, so the table answers "how much is forty-two, added to itself, again and again?"
Built from the ground up, the ladder looks like this:
$42$
$42 + 42 = 84$
$42 + 42 + 42 = 126$
$42 + 42 + 42 + 42 = 168$
Multiplication is the shortcut for that stacking, which is why $42 \times 4$ and "four forty-twos added together" both give 168.
What Are The Multiples Of 42?
The multiples of 42 are the numbers you land on when you skip-count in forty-twos. The first twenty are:
42, 84, 126, 168, 210, 252, 294, 336, 378, 420, 462, 504, 546, 588, 630, 672, 714, 756, 798, 840.
Every entry in the table of 42 is a multiple of 42, and each is also a multiple of 2, of 3, of 6, of 7, of 14, and of 21, because $42 = 2 \times 3 \times 7$. That rich set of factors is why every product is even and why the 42 table connects to so many smaller ones.
How To Learn The 42 Times Table (Patterns, Not Memorizing)
Bhanzu teaches the few patterns that generate a table rather than drilling its facts into recall. The table of 42 grows straight out of tables you already know, so a student can rebuild any row by reasoning instead of memorizing it. Seeing $42 = 6 \times 7$ live inside every product is the factor-thinking that fractions and algebra later reward.
Every pattern below comes from how 42 is built: $42 = 6 \times 7$, $42 = 2 \times 21$, and $42 = 40 + 2$.
Pattern 1: Ride the 6s or the 7s. Because $42 = 6 \times 7$, you get $42 \times n = 6 \times (7n)$ or $7 \times (6n)$. For $42 \times 4$, take $7 \times 4 = 28$ from the 7 times table, then $\times 6 = 168$, or take $6 \times 4 = 24$ from the 6 times table, then $\times 7 = 168$.
Pattern 2: Double the 21s. Since $42 = 2 \times 21$, every multiple of 42 is double the matching multiple of 21. For $42 \times 5$: $21 \times 5 = 105$, doubled is $210$.
Pattern 3: Split by place value. Read 42 as $40 + 2$, so $42 \times n = 40n + 2n$. For $42 \times 7$: $40 \times 7 = 280$ and $2 \times 7 = 14$, giving $280 + 14 = 294$.
Pattern 4: Every product is even, ending in 2, 4, 6, 8, 0. Because 42 is even, so is every multiple, and the ones digits cycle 2, 4, 6, 8, 0. An odd ones digit means a slip somewhere.
How Do You Read And Use The Table Of 42?
Read each row left to right: $42 \times 6 = 252$ is "forty-two taken six times gives two hundred fifty-two." The first number is the group size, the second is how many groups, and the product is the total.
To learn it, lean on the 6s and 7s you already trust, then quiz yourself out of order so you are recalling facts rather than reciting a chant. The double-the-21s method is your safety net, so if a row slips, rebuild it from the 21 table and double.
Where Does The Table Of 42 Appear?
Forty-two is a "weeks into days" number, since $6 \times 7 = 42$ means six full weeks is exactly 42 days, so any six-week plan or pregnancy-trimester count runs on this table. It also sizes standard server racks, which hold 42 rack units, so a data-centre technician counting capacity across cabinets is reading the 42 table. And a barrel of crude oil holds 42 US gallons, which is why refinery output scales along these multiples.
Solved Examples Of The Table Of 42
Example 1
What is $42 \times 6$?
Split 42 into $40 + 2$.
$40 \times 6 = 240$
$2 \times 6 = 12$
$240 + 12 = 252$
Final answer: $42 \times 6 = 252$.
Example 2
A crate holds 42 apples. How many apples fill 9 crates?
Wrong attempt. The rusher reads $42 \times 9$ as just $4 \times 9 = 36$ and stops there.
Why it breaks. Nine crates of forty-two apples must hold far more than a single crate, so 36 cannot be right; it is less than even one crate's 42.
Correct. Split 42 into $40 + 2$ and use both parts.
$(40 \times 9) + (2 \times 9) = 360 + 18 = 378$
Final answer: 378 apples.
Example 3
Find $42 \times 12$.
Split it: $42 \times 10 = 420$ and $42 \times 2 = 84$.
$420 + 84 = 504$
Final answer: $42 \times 12 = 504$.
Example 4
$42 \times {?} = 588$.
Divide to find the missing factor: $588 \div 42 = 14$.
Final answer: $42 \times 14 = 588$.
Example 5
Use the factor pair to find $42 \times 5$.
Take the 21 table and double it, since $42 = 2 \times 21$.
$21 \times 5 = 105$, then $105 \times 2 = 210$
Final answer: $42 \times 5 = 210$.
What Are Common Mistakes With The Table Of 42?
Mistake 1: Dropping the ones digit
Where it slips in: Treating 42 as if it were 40 and forgetting the extra $2n$.
Don't do this: Writing $42 \times 9 = 360$ (just the $40 \times 9$).
The correct way: Add the units part: $360 + 18 = 378$. The 2 in 42 still contributes on every row.
Mistake 2: Landing on an odd product
Where it slips in: Rushing a middle row and writing an odd ones digit.
Don't do this: Answering $42 \times 7 = 293$.
The correct way: $42 \times 7 = 294$. Since 42 is even, every product must end in 2, 4, 6, 8, or 0.
Practice Questions On The Table Of 42
$42 \times 3 = {?}$
$42 \times 8 = {?}$
Fill in the blank: $42 \times {?} = 420$.
A box packs 42 crayons. How many crayons in 6 boxes?
$42 \times 11 = {?}$
Which is larger, $42 \times 9$ or $42 \times 8$?
$42 \times 20 = {?}$
Use the 6 and 7 factor pair to find $42 \times 4$.
Answers: 1. 126 2. 336 3. 10 4. 252 5. 462 6. $42 \times 9 = 378$ is larger 7. 840 8. 168.
Conclusion
The table of 42 is really the sixes and sevens working together, from $42 \times 10 = 420$ to $42 \times 20 = 840$, so once you see $6 \times 7$ inside every product you can rebuild any row without memorizing it. Keep the double-the-21s and split-into-$40 + 2$ patterns close, and the even-number check will catch most slips.
