Answer below:
In this matchstick puzzle, relocating 1 matchstick from the left side to the right side will aid you in finding a solution.
Given the equation 8 + 3 – 4 = 0 represented with matchsticks,
Take a matchstick from the first digit 8 to transform it into the digit 9 and place it on the right side to maintain 8.
This adjustment yields:
9 + 3 – 4 = 8
Thus, the solution to the puzzle is:
Left-hand side (LHS) = 9 + 3 – 4 = 12 – 4 = 8
Right-hand side (RHS) = 8
Therefore, LHS equals RHS.
Answer 2:
Pick a stick from the first number 8 so it turns to a number 6 and put that in the number 4 so it becomes 9.
LHS = 6+3-9=9-9=0
RHS = 0
LHS = RHS
Answer 3:
Pick a stick from the third number 4 so that it transforms to form number 11.
LHS = 8+3-11=11-11=0
RHS = 0
LHS = RHS
