A chess board has 64 squares. If pieces occupy 19 squares, how many squares are unoccupied?
64 - 19 = ?
45 But this is NOT an algebra problem it is but a simple subtraction problem.
To find the number of squares that are unoccupied on a chessboard, you can subtract the number of squares occupied by pieces from the total number of squares on the board.
In this case, we have a chessboard with 64 squares and 19 squares occupied by pieces. To determine the number of unoccupied squares, we subtract 19 from 64:
64 - 19 = 45.
So, there are 45 squares that are unoccupied on the chessboard.
