If you have a child who is struggling with multiplication (or just loves learning new things), then this trick could be pretty handy (pun intended).
Now, there’s always good old memorization, but sometimes it’s helpful to know that you have a built-in cheat sheet.
Note: This only works for 6*, 7, 8 and 9 times tables, but those are typically the most challenging ones. *This trick does not work for 6×6.
- Staring with your pinkie fingers and working your way to your thumb, number your fingers from 6 through 10.
- Line up the fingers that correspond to your math problem. For example: when multiplying 7 x 8, line up the correct numbered finger on each hand. See example below:
Now that you have your fingers lined up, here is where the magic happens.
- Add the two lined up fingers and the ones below it. For this example, it would be 5 fingers. This number will be the first number in your final answer (the number in the 10’s column, so here, 5 = 50).
- Now multiply the top fingers on your left hand by the top fingers on your right hand. Here, it would be 3 x 2. This equals 6. This is the second number in your final answer (the number in the 1s column).
- Combine the two numbers and you have your answer: 56. Pretty cool!
This is just one of many ways to make learning math a little easier It can’t hurt to try it, right?
