Is the product of 21 negative numbers and 23 positive numbers a positive number or a negative number?
Well, honey, buckle up because we're diving into some math! When you multiply an odd number of negative numbers, the product is negative. Since 21 is an odd number, the product of 21 negative numbers will be negative. And since 23 is an odd number as well, the product of 23 positive numbers will also be positive. So, when you multiply them together, you get a negative number. Math, ain't it a peach?
