Here is a matchstick equation which is obviously wrong.
18019=1
Make the equation correct by moving "fewest" matchsticks (my solution involves 3 moves).
You may use numbers, letters, Roman Numerals but only as below
1 matchstick used for - or / (subtract or divide)
2 Matchsticks used for I and 1 AND +, =, X (multiply)
3 for L,T,Y and 7
4 for C,F,J,K,V,X,Z AND 4
5 for E,H,P,S,U and 2,3,5
6 for A,D,G,M,N,O,R,W and 0,6,9
7 for B,Q and 8
You can use spaces between numbers to insert only one thing like function or number. **
