Some multiplication facts are also tricks that may help students in the quest for faster factoring without memorization for the numbers one through twelve.

The easiest multiplication rule to remember is the factors of one, which is that any number multiplied by one remains the same.

When a number is multiplied by two, it can also be viewed as being added to itself, for example: 2x6=12 and 6+6=12.

For the number three, a quick trick can help check the accuracy of your work, but will not speed up the multiplication.

Every multiplication answer of three will add up to three, six, or nine, if an answer does not add up to one of these numbers, then it is incorrect; for example: 2x3=6 and 3+3=6, or 3x12=36 and 3+6=9.

One and zero are easy multiples to memorize, and five is just as simple.

Each multiple of five is exactly five higher or lower than the next or last multiple factored, for example: 0x5=0, 1x5=5, 2x5=10, and consequently, 0+5=5, 5+5=10, and 10+5=15.

Another fun multiplication trick is with the number six, but only works with even numbers.

When six is multiplied by an even number, the answer will always end with the same number that is multiplying six: 6x2=12, and 6x8=48.

Multiplication tricks continue with the number nine, which has more than one way to factor faster.One can factor what the number being multiplied to nine is by first using multiplication by ten and then subtracting the multiplier from that answer, 9x3=10x3-3.

Nine has another quick trick as shown in the example, 9x3=27, where 3-1=2 and 2+7=9, the answer is 27; simply revert back to the previous number and then count up to nine.

The multiplication tables of ten are as easy to learn as adding a zero to the number that is being multiplied: 10x2=20, 10x9=90, and 10x15=150.

Doubling up is all one needs to do when multiplying by the number eleven (for all whole numbers up to nine); such as, 2x11=22 and 5x11=55.

For the numbers ten through eighteen, another multiplication trick can be applied with the number eleven.Take the sum of the multiplying number and write it between the number itself to reveal the answer, 11x17=1 (1+7) 7, 187.

The number twelve has a multiplication trick that requires recall of the multiplication table for ten.Add together the results of multiplying the number by ten and two, to arrive at the answer: 12x5=60 and (10x5) + (2x5) =60.

Flash cards are a great quizzing tool for recalling the multiplication tables, but tips and tricks will assist factoring in examination and in real life applications.
