There are no real numbers that will answer this question, just imaginary numbers. The imaginary numbers are 1+sqrt(-2) and 1-sqrt(-2), which we normally write as 1+2i and 1-2i where i stands for the sort of (-1) (1+2i) + (1-2i) =2 (1+2i) * (1-2i) = 3 (note * stands for multiply)
They are positive numbers. They are integers. They are natural numbers. They are whole numbers. ____________ They are also rational numbers (4= 4/1; 5=5/1; 6=6/1; 7=7/1; 8= 8/1). The / stands for a fraction if you didn't know.
It stands for the quotient. The letter R stands for the set of Real numbers.
There are more composite numbers than prime numbers because most numbers have more factors than just 1 and a number itself.
