The leftmost bit which is used for sign helps figuring if we deal with a positive number or a negative number. If the number is positive, the sign bit is 0, otherwise, if it is 1, then the number is negative. For example, -25 in signed-magnitude 8-bit binary is: 1001 1001, while +7 in the same representation is 0000 0111....
