That is changing. New research from the National Academy of Sciences suggests that's no longer the case: scientists can now determine with some confidence the degree climate change influenced some extreme weather events.
The factors are the numbers that are being multiplied together. The product is the result or answer of multiplying the multiplicand by the multiplier. A multiplication problem may be written horizontally such as 2 x 7 = 14. In this example 2 and 7 are the factors and 14 is the product of the multiplication. A multiplication problem may be written vertically. 2 x 7 14.
There is only no solution when you come up with an answer that is undefined (i.e. a number divided by zero, the square root of a negative number, etc.). There is a solution when you end up with any actual value (in your case 0). Your answer is x=0.
