Answer:
When you multiply two numbers with the same sign (either both positive or both negative), the rule is that the result is always positive.
For example, if you multiply +2 and +3, the result is +6 because both numbers have the same positive sign. Likewise, if you multiply -4 and -5, the result is +20 because both numbers have the same negative sign.
This rule applies to any two numbers with the same sign, regardless of their values or whether they are whole numbers, fractions, or decimals.
