If z is a vector or a matrix, sign (z) returns the sign of each element of z. Examples Signs of Real Numbers Find the signs of these symbolic real numbers: [sign (sym (1/2)), sign (sym (0)), sign (sym (pi) - 4)]Summarizing, we have: ( 2 positive units) + ( 3 positive units) = ( 5 positive units) Now let us add the two negative numbers − 2 and − 3. We perform this addition on the number line as follows. We begin at 0, the origin. Since − 2 is negative, we move 2 units to the left. Since − 3 is negative, we move 3 more units to the left.

2. Bold version of real number symbol.
