**No, 33 is not divisible by 2.**It will leave a comma spot.- Divisibilty rule for 2 is: Units are divisible by two if the last digit is even. Even numbers for 2 are (0,2,4,6,8).

- Thirty-three divided by two is 16.5. Math: 33÷2=16.5

- First, take any number (for this example it will be 376) and note the last digit in the number, discarding the other digits. Then take that digit (6) while ignoring the rest of the number and determine if it is divisible by 2. If it is divisible by 2, then the original number is divisible by 2.
- Example: 376 (The original number).
~~37~~__6__(Take the last digit). 6÷2 = 3 (Check to see if the last digit is divisible by 2) 376÷2 = 188 (If the last digit is divisible by 2, then the whole number is divisible by 2).

**About Number 3.**Three is the first odd prime number and the second smallest right after number two. At the same time it is the first Mersenne prime (2 ^ 2-1), the first Fermat prime (2 ^ {2 ^ 0} +1), the second Sophie Germain prime and the second Mersenne prime exponent. It is the fourth number of the Fibonacci sequence and the second one that is unique. The triangle is the simplest geometric figure in the plane. With the calculation of its sizes deals trigonometry. Rule of three: If the sum of the digits of a number is a multiple of three, the underlying number is divisible by three.

A divisibility rule is a shorthand way of determining whether a given number is divisible by a fixed divisor without performing the division, usually by examining its digits. Although there are divisibility tests for numbers in any radix, and they are all different, this article presents rules and examples only for decimal numbers. For divisors with multiple rules, the rules are generally ordered first for those appropriate for numbers with many digits, then those useful for numbers with fewer digits.
