In mathematics

It is the second number of the tenth row of a skewed Fibonacci-Pascal triangle (sequence A037027 in OEIS).

235 is the concatenation of the base 10 representations of the first three primes, and thus it is a Smarandache–Wellin number.

235 is from the subset of numbers that have exactly two nontrivial prime factors, neither of which is two or three, namely 235 = 5 X 47. Thus, 235 is also a square-free number.

In other fields

235 is also:

• The atomic mass number of an important isotope of the element uranium, U-235, the fissile isotope which is used as the fuel for nuclear reactors and in some nuclear weapons. The atomic mass number results from each nucleus of U-245 containing 92 protons and 143 neutrons, and 92 + 143 = 235.

• The number of three interstate highways in the United States, located in the states of Iowa, Kansas, and Oklahoma. See: Interstate 235.
