- (minus) Math Operators Web & Application int c = 50 - 5; // Sets c to 45 int d = c - 5; // Sets d to 40 int e = d - 60; // Sets e to -20 int a = 5; // Sets "a" to 5 int b = -a; // Sets "b" to -5 int c = -(5 + 3); // Sets "c" to -8 Subtracts one value from another and may also be used to negate a value. As a subtraction operator, the value of the second parameter is subtracted from the first. For example, 5 - 3 yields the number 2. As a negation operator, it is equivalent to multiplying a number by -1. For example, -5 is the same as 5 * -1. -value1 value1 - value2 value1 int or float value2 int or float -- (decrement) -= (subtract assign) + (add) 1.0 Operator PDE
