What is the additive inverse of -21?
The additive inverse of a number is the value that, when added to the original number, results in zero. In this case, the additive inverse of -21 would be 21, as -21 + 21 equals zero. The additive inverse is essentially the negative of the original number, so the additive inverse of -21 is 21.
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?
If 21 divides into M what else must dive into M?
If 21 divides into M then all the factors of 21 must divide into M.The factors of 21 are 1, 3, 7, 21 (we usually avoid the factor 1 and the number)So, 3 and 7 must divide into M.
