Because lots of nothing is still exactly nothing.
0
0x0=0
Anything multiplied by 0 is 0, so there is no value you can multiply by 0 that will give you 270.
Multiply any number with 0, you get 0.
When you multiply something by four, you quadrupleit.
If you multiply anything by 0, it will equal 0. Always.
0
It depends. If you start with a positive number, then multiply by a positive greater than one and the answer is greater; multiply by 1 and the answer is the same; multiply by a number between 0 and 1 and the answer is smaller; multiply by 0 and the answer is 0; multiply by a number less than 0 and the answer is negative.
0x0=0
Anything multiplied by 0 is 0, so there is no value you can multiply by 0 that will give you 270.
Multiply any number with 0, you get 0.
0 * (-1) = 0
When you multiply something by four, you quadrupleit.
None. Division by 0 is not permitted and, as soon as you multiply by 0, everything becomes 0.
No, because no matter what you multiply with 0, your answer will always be 0.
yes
It is the multiplicative inverse (of the something).
