It is: 235+120 = 355
It is a composite number because it has more than two factors
235 is itself a real number.
235 is a composite number because it has more than two divisors - contrary to a prime which has exactly two divisors: 1 and the prime itself. 235 has 4 divisors: 1, 5, 47 and 235. A quick way to determine this is done by looking at the last digit. If it is either 0 or 5 the number is divisible by 5, thus it is not a prime.
The number is bigger than 5 but ends in 5 so it is divisible by 5. Therefore it cannot be a prime.
If you mean: 2, 3 and 5 then they are 71, 73, 77 and 79
235 + 10 = 245
757 - 235 = 522
It is a composite number because it has more than two factors
If you mean 3235 then it is a composite number because it has more than two factors
0.235 is greater than 0.234.

235-92 = 143
Uranium 235 has 92 protons and 92 electrons. To find the number of neutrons, follow this equation: Mass # - Atomic # = # of neutrons. Since the mass number of uranium 235 is 235 and has an atomic number of 92, the number of neutrons is 143.
All isotopes of uranium have the same number of protons, 92. A nuclide with a number of protons other than that is not uranium.
Uranium-235 is the element with a mass number of 235. It is a radioactive isotope of uranium that is used in nuclear reactors and nuclear weapons.
Like all isotopes of uranium (identified by the "mass number" following the element name--235, in this case), U 235 has the atomic number 92. An element name is really just a more memorable way to designate a specific atomic number. This is because different isotopes with the same atomic number such as U 238 (the common type) and U 235 (a rare type)--or, to take a more common example, Carbon 12 (the common kind) and the slightly radioactive Carbon 14 (extremely rare), share the same number of electrons with all weights of the element. To put it another way, an isotope identified by a mass number (235 or 238) is just a slightly leaner or heavier version of the same atomic number. So, even though U 238 has three more neutrons in its nucleus than does U 235, the two have the same atomic number; which is just another way of saying they are the same element. The number of electrons determines how an element behaves chemically and that's how element names are assigned. Elements are sorted by chemical interaction characteristics, not by weight: weight. The mass number (in this question, 235) is a subdivision of element/atomic number. If an element has the same name, but a different mass number, all elements with that name share the same atomic number.
