You can actually count up to 1023 using your fingers! This is done through a clever method called binary counting, where each finger represents a power of two. Basically, each of your 10 fingers represents a place value in the binary system.

• Right thumb: $2^0=1$
• Right index finger: $2^1=2$
• Right middle finger: $2^2=4$
• Right ring finger: $2^3=8$
• Right pinky: $2^4=16$
• Left thumb: $2^5=32$
• Left index finger: $2^6=64$
• Left middle finger: $2^7=128$
• Left ring finger: $2^8=256$
• Left pinky: $2^9=512$

Counting:

• Start with all fingers down (this represents zero).
• To count, raise fingers corresponding to the binary place values that add up to the number you want to represent.
• For example:
  • 1 is represented by raising your right thumb.
  • 3 is represented by raising your right thumb and index finger (1 + 2).
  • 81 is represented by raising your right thumb and right pinky and left index finger (1 + 16 + 64).
