Great Multiplication Strategy

Ever had problems with massive multiplication problems? well this method is fast, easy and will solve every multiplication problem in no time! all you will need are these simple instructions. It is easy to set up, it is easy to get the hang of and it is easy to teach.

Steps/What to do


  • First, you choose 2 digits and plot them on a line. (It dose not have to be 2 digit. it can be 6,5,4,3,2 and 1, even bigger)

15

28 x



  • Next, you multiply the top ones by the bottoms ones.

4

15

28 x

120

8x5=40 8x1=8+4=12

(you must plus the 4 from the 40 that you made before, you also put the answer that you got under the last number)



  • Do it again.....

1

4

15

28 x

120

300

2x5=10 2x1=2+1=3

(Add and extra 0 because you up to you second digit. If you were up to you third 0 you would put two 0's, if you were up to your 4th you would put three 0's and so on and so on)



  • Now you must add up all your answers and then you get your grand answer.

120

300 +

420


So there you go, that is how to do the algorithm. Its fast, Simple, Easy, Cool and really easy to memorize. You have just learnt one of the the most simple multiplication problem solving strategy in the world!
