Working with simple addition and multiplication of positive and negative numbers. Have completed 59 of 60 problems on a worksheet, I am stumped by one of them. For example Two numbers are given 30 and 13, You must find two number multiplied together equal 30 and when added equal 13, simple enough two numbers are 15 and 2. Cant solve this on. Two numbers added must equal 1, but if multiplied equal 30, Help please.
