The answer is -15. Here are the sign rules to multiplication. If you multiply two numbers with the same sign, the result will be positive. If you multiply two numbers with opposite signs, the result will be negative.
the two numbers are 50.54657341 and -8.546573405 That was a good try. The two numbers do add up to 42, but unfortunately the product of a positive and a negative is negative, so that they multiply to give -432 rather than 432. The correct answer is 18 and 24
