1) Addition and Reduction

Right hand and left hand as a unit as tens.

Right Hand:
- Index finger opens = 1
- (Index finger middle finger) opened = 2
- (Middle finger index finger ring finger) opened = 3
- (Middle finger index finger ring finger little finger) opened = 4
- (Middle finger index finger ring finger little finger) Thumb closed opened = 5
- (Thumb index finger) opened = 6
- (Thumb forefinger middle finger) opened = 7
- (Thumb forefinger middle finger ring finger) opened = 8
- (Thumb forefinger middle finger ring finger little finger) opened = 9

Left Hand:
- Forefinger opened = 10
- (Index finger middle finger) opened = 20
- (Middle finger index finger ring finger) opened = 30
- (Middle finger index finger ring finger little finger) opened = 40
- (Middle finger index finger ring finger little finger) Thumb closed opened = 50

3) Addition and Reduction

Common terms:
ADDED = UP finger
LESS = DOWN finger

To increase the number under 5 with no more than 10 results, simply operate the right hand only (UNITS)

- 1 1 = 2 = raise your index finger; raise your middle finger
- 1 2 = 3 = raise your index finger; raise your middle finger; raises Jari Manis
- 1 4 = 5 = raise your index finger; raise the thumb; lower the index finger again
explanation:
because 4 is 5 (Thumb UP) subtract 1 (DOWN index finger) so that the above equation becomes:
1 4 =
1 (5-1) =
A 5-1 =
Thumbs UP UP DOWN index finger index finger =
5 =
thumb

- 5 1 = 6 = RIDE UP thumb index finger
- 5 2 = 7 = Thumbs UP UP UP Forefinger Central
- 5 3 = 8 = Thumbs UP Central UP UP UP Forefinger Sweet
- 5 4 = 9 = RIDE UP thumb forefinger Central UP UP UP Sweet little finger
