If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative. Multiplying a positive number by a negative number, or a negative number by a positive number, results in a negative result.For addition, if you add two positive numbers, the result is positive. If you add two negative numbers, the result is negative. If you add a positive and a negative number, the result depends on which of the numbers has the greater absolute value. For example, if the positive number has the greater absolute value (distance from zero), the result will be positive.If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative.

Take 476 and divide it by 2. Now take that result and add it to 476. Hey presto, you've got your answer.
If you add an even number to an even number, you will have an even number as a result.
you add the number (in this case, 6) to the beginning of the continuously growing number : the answer is 654326
The result is an odd number.
