Negative numbers
Even numbers greater than two
Zero and one
Real numbers, imaginary numbers and irrational numbers are three kinds of numbers. Others are rational numbers, algebraic numbers and primes numbers. There are many more.
kinds of numbers are like 1,2,3,4,5,6,7,8,9,10
They are all single digit numbers.
Roman numerals and just plant numbers
Natural numbers or Counting numbers Integers Rational numbers Irrational numbers
Complex numbers include real numbers, pure imaginary numbers, and the combination of those two.
The "two" kinds of energy are real and vector energy. Mot accounting for the two kinds of energy is the cause of current confusion in physics. Newton and Einstein missed the two kinds of energy real and vector. The gravitational energy is E= -mu/r + mcV. The first kind of energy Newton got the real or potential energy -mu/r. The unaccounted for energy is the "vector" energy mcV. The vector energy is the source of "dark energy" and myriad mysteries in cosmology. The Universe has two kinds of numbers, real numbers and vector numbers. This gives two kinds of energy, and two kinds of forces ,etc,etc,etc. Quaternions are the answer to the "two kinds" of energy, "reals and vectors" or quaternions!
Gay ones.
2 kinds of food hahahahhaha
The theory of numbers is based on the property of sets of different kinds of numbers.
They are whole numbers,counting numbers,integers,rational numbers,real Numbers,composite numbers,square numbers,positive numbers,2-digit numbers.
