- _ _ _ MINUSSIGN _ _ _ _ _ _ _ _ _ _ _ _ operator
The - operator is a prefix or infix binary subtraction operator, as wel l as the unary minus operator.
<expression> may be any valid REDUCE expression.
15 - 4; 11 x*(-5); - 5*X a - b - 15; A - B - 15 -(a,4); A - 4
The subtraction operator is left associative, so that a - b - c is equivalent to (a - b) - c, as shown in the third example. The subtraction operator is also valid with matrix expressions of the correct dimensions and with equations.
