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.
Y = solve(eqns,vars) solves the system of equations eqns for the variables vars and returns a structure that contains the solutions. If you do not specify vars, solve uses symvar to find the variables to solve for. In this case, the number of variables that symvar finds is equal to the number of equations eqns.
