What happens when you multiply a number by 0?
When you multiply a number by zero you actually will always get zero because zero means nothing at all
Why it is that any number multiply by zero is equal to zero?
In layman's terms: if zero is the primary number and you were to multiply that primary number to any number, it's still zero. Multiplying 1 times 1 equals to 1. One times itself is one. So zero, meaning nothing times 1 is equal to nothing since there is nothing to begin with.
Can 0 be the identity for multiplication?
No. The identity for multiplication is the number 1. If you multiply a number by 1, then the product is the original number. If you multiply a number by zero, the product is zero, so the number has 'lost it's identity'
What is the sum of any rational number and its opposite?
If we define "opposite" as the additive inverse, the sum is zero.
What is the opposite of 0.1?
The opposite of 0.1 is -0.1. In mathematics, the opposite of a number is the number that, when added to the original number, equals zero. Since 0.1 is a positive number, its opposite would be a negative number with the same magnitude but in the opposite direction on the number line.
