The Roman Counting Game

The Romans counted on their fingers. The Roman numerals are NOT letters. They may look like letters... but they are not! They are symbols for fingers of the hand:

I is one finger
II is two fingers
III is three fingers
IIII is four fingers
V is five fingers (a schematic view of "V" made by hand with all fingers extended; see below)
VI is six fingers
VII is seven fingers
VIII is eight fingers
VIIII is nine fingers
X is ten fingers (a schematic view of two hands, wrist to wrist, all fingers extended)

The use of "IV" to indicate 4 came later, and IIII continued to be used as a representation of the number 4 (it makes sense, doesn't it?).

Now learn how to multiple numbers 5 and higher using finger counting! Here is an illustrated guide to the Roman counting game which lets you multiply numbers 5-9 on your fingers.

LEFT  
RIGHT
To show the number 5,
hold no fingers down,
palm facing you:
To show the number 6,
hold one finger down,
palm facing you::
To show the number 7,
hold two fingers down,
palm facing you::
To show the number 8,
hold three fingers down,
palm facing you::
To show the number 9,
hold four fingers down,
palm facing you::

To multiply, do the numbers with both hands, and then COUNT the number of fingers down and multiply those by 10, and then MULTIPLY the number of fingers standing up, and then add the two numbers:

6 multiplied by 7:

3 fingers down = 30
4 x 3 fingers up = 12

TOTAL 42

9 multiplied by 9:

8 fingers down = 80
1 x 1 fingers up = 1

TOTAL 81

7 multiplied by 8:

5 fingers down = 50
3 x 2 fingers up = 6

TOTAL 56

8 multiplied by 5:

3 fingers down = 30
2 x 5 fingers up = 10

TOTAL 40
