Here, we give you free printable multiplication table PDFs and go over the nine rules you should know about multiplication. Multiplication Table 12 x 12 Below is a 12 x 12 multiplication chart showing all multiples of the numbers 0-12. To use this chart, look for the two numbers youwant to multiply together on the top row and in the leftmost column, and then find the box that connects these two numbers together. For example, if you’re trying to find the product of 7 and 5, you'd look for 7 in the leftmost column and 5 in the top row, and then see where these two meet in the middle (35). (You can also look for 7 in the top row and 5 in the left column- as we’ll explain, the order in which you multiply doesn’t actually matter!) 0 1 2 3 4 5 6 7 8 9 10 11 12 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 1 2 3 4 5 6 7 8 9 10 11 12 2 0 2 4 6 8 10 12 14 16 18 20 22 24 3 0 3 6 9 12 15 18 21 24 27 30 33 36 4 0 4 8 12 16 20 24 28 32 36 40 44 48 5 0 5 10 15 20 25 30 35 40 45 50 55 60 6 0 6 12 18 24 30 36 42 48 54 60 66 72 7 0 7 14 21 28 35 42 49 56 63 70 77 84 8 0 8 16 24 32 40 48 56 64 72 80 88 96 9 0 9 18 27 36 45 54 63 72 81 90 99 108 10 0 10 20 30 40 50 60 70 80 90 100 110 120 11 0 11 22 33 44 55 66 77 88 99 110 121 132 12 0 12 24 36 48 60 72 84 96 108 120 132 144 We also offer two free printable PDFs of this 12 x 12 multiplication chart.

Time to turn on your brain! 9 Fundamental Rules for Remembering Multiples As you use the multiplication table above, make sure you know all the basic rules for remembering multiples and how they work. Below, we go over the most common multiplication rules you should have memorized. Rule 1: Order Doesn’t Matter in Multiplication If all you’re doing is multiplying two or more numbers together- and aren’t doing any other math function such as adding, subtracting, or dividing- then the actual order of those numbers doesn’t matter. In other words, 8 x 4 is the same exact problem as 4 x 8 (both equal 32). This rule also works if you’re multiplying more than two numbers together. For example, 2 x 3 x 4 can be written as 2 x 4 x 3, 3 x 4 x 2, etc. Regardless of the order of the numbers being multiplied, this equation will always come out to 24. This means that with the multiplication chart above, you may look for numbers in either the top row or the leftmost column. It doesn’t matter whether you’re connecting the 8 in the top row and the 4 in the left column, or the 8 in the left column and the 4 in the top row. Both ways will give you the same answer of 32. Note, however, that the order doesmatter when you’re doing more than just multiplying numbers together.For example, if you’re multiplying and adding numbers in a problem, you’ll need to follow the order of operations to solve it correctly. Many people use the acronym PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction) to help them recall the correct order in which they must perform calculations to solve a math problem. An easy way toremember this acronym is with the phrase, "Please excuse my dear Aunt Sally." Rule 2: All Multiples of Even Numbers Are Even No matter which even number you choose- whether it’s as low as 2 or as high as 33,809,236- all multiples of even numbers will always be even as well. Don’t believe me? Just look back at the multiplication table above. If you look at the column under 6, for example, you’ll see that all multiples of 6 are, in fact, even numbers! These multiples include 12, 18, 24, 30, 36, etc. A number is even if the digit in the ones place is even (in other words, if it ends in 0, 2, 4, 6, or 8). This rule works because whenever you multiply an even number by another even number or by an odd number, the product will always be even.Here are the formulas that illustrate this: even x even = even even x odd = even Rule 3: All Multiples of Odd Numbers Follow an Even-Odd Pattern Unlike Rule 2, all multiples of odd numbers aren’t, in fact, odd! Rather,multiples of odd numbers will always follow an even-odd pattern. What do I mean by this? Let’s look at an example. Take the odd number 7. Below are the multiples of 7. Each multiple has been highlighted in either yellow (even) or blue (odd): 0 1 2 3 4 5 6 7 8 9 10 11 12 7 0 7 14 21 28 35 42 49 56 63 70 77 84 As you can see, the multiples of 7, an odd number, follow a clear pattern of even, odd, even, odd, and so on. This pattern works because of a fundamental rule in math: an odd number multiplied by an even number will always be even, but an odd number multiplied by an odd number will always be odd. Here are the formulas to help you remember this concept: odd x even = even odd x odd = odd Nature has patterns just like math does. Rule 4: The Only Multiple of 0 Is 0 As you likely noticed in the multiplication chart above, any time you multiply 0 by a number- whether that number is 5, 0.0004758, or 6,783,390,391- the product will always equal 0. Basically, since any number times 0 is equal to 0, all multiples of 0 are therefore 0 as well. Rule 5: A Multiple of 1 Always Equals the Number Being Multiplied Whenever a number- no matter how small or big it might be- is multiplied by 1, the answer will be equal to the original number you started with. For example, 9 x 1 = 9.And 12,351 x 1 = 12,351. Here are some multiples of 1 taken from the chart above: 1 2 3 4 5 6 7 8 9 10 11 12 1 1 2 3 4 5 6 7 8 9 10 11 12 Rule 6: All Multiples of 5 End in 0 or 5 If you look at the multiplication chart above, you’ll notice that all multiples of 5 end in either a 0 or 5. Knowing this makes it easy to remember what numbers are multiples of 5, even if they’re super high. In short, anything that ends in a 5 or 0 is for sure a multiple of 5. Here is a small chart showing some of the multiples of 5: 0 1 2 3 4 5 6 7 8 9 10 11 12 5 0 5 10 15 20 25 30 35 40 45 50 55 60 Rule 7: For Multiples of 10, Just Add a 0 To find a multiple of 10, all you need to do is add a 0 to the end of the number being multiplied by 10. So if you have the problem 10 x 27, you should know right away that the answer is 270 (27 with a 0 added to the end of it). This rule also means that all multiples of 10 end in 0 (this is similar to Rule 6, which states that all multiples of 5 end in either a 5 or 0). In other words, any number you see that ends in a 0, whether it’s 640 or 4,328,120, will be a multiple of 10. Here’s a chart showing some common multiples of 10: 0 1 2 3 4 5 6 7 8 9 10 11 12 10 0 10 20 30 40 50 60 70 80 90 100 110 120 Zerocan be a very useful number in multiplication. Rule 8: Up to 11 x 9, All Multiples of 11 Are Repeated Digits As the multiplication table above shows, all multiples of 11 up to 11 x 9 are equal to the digit being multiplied repeated once. So if you multiply 11 by 6, for example, the answer will be 66 (you just repeat 6- the number being multiplied by 11). Note that this trick only works up to factor 9. Once you hit 10, the product will not equal two repeated digits. Here are the multiples of 11 using the factors 1-9: 1 2 3 4 5 6 7 8 9 11 11 22 33 44 55 66 77 88 99 Rule 9: For 12, Multiply by 10 and 2 Then Add Together Multiples of 12 can be difficult to memorize and a little overwhelming, but there’s an easy trick you can use to quickly find any multiple of 12. All you have to do is multiply the factor (the number being multiplied by 12) by 10, multiply that same factor by 2, and then add these together. This might sound complicated, but it’s really not! Written out as an equation (in which a is any factor of 12), this trick would look like this: 12a = 10a+ 2a Let’s walk through an example. Say you want to find the product of 12 x 9. The quickest way to do this would be to first multiply 9 by 10; this gives us 90.Next, multiply 9 by 2 to get 18. Finally, add together 90 and 18. This gives us108, which is the answer to our original problem: 12 x 9. Try this trick with other factors and then double-check your answer with the multiplication chart or a calculator. What’s Next?
