The above equation is not true. Move only 3 matchsticks to make it true.

      Yes Nirup, also correct. Would require moving only 2 matchsticks.

    4+7+0=11
    moving the two sticks from the 1 in 14 to the 4 and taking the middle of number for to make 0

    14 - 7 + 4 =11

    14 + 1 - 4 = 11¹ (one move)

    14 ++1 - 4 = 1¹ ? (one move)
