When two negatives are multiplied together, the answer is positive.
The expression you provided is "- * -". To evaluate this expression and determine its value, we need to understand the order of operations in mathematics.
In mathematics, multiplication takes precedence over subtraction. So, when we encounter a subtraction symbol, we can think of it as adding the opposite. In this case, the expression "- * -" can be rewritten as "-1 * -1".
When we multiply two negative numbers together, the result is always positive. So, "-1 * -1" is equal to +1.
Therefore, the value of the expression "- * -" is +1.
