... 34. If a no. ‘N’ has got k factors and a^l is one of the factors such that l>=k/2, then, a is the only prime factor for that no. 35. To find out the sum of 3-digit nos. formed with a set of given digits This is given by (sum of digits) * (no. of digits-1)! * 1111…1 (i.e. based on the no. of digits) ...

... How can we determine the base-2 representation of a number? Let’s go through it for 1/10 a little more carefully. First, 1/10 < 1/2, so the first digit is 0 (we have no halves). Next, 1/10 < 1/4, so the next digit is also 0 (no quarters, either). Also, 1/10 < 1/8, so the next is 0 as well. But, 1/10 ...

Elementary arithmetic
Elementary arithmetic is the simplified portion of arithmetic that includes the operations of addition, subtraction, multiplication, and division. It should not be confused with elementary function arithmetic.Elementary arithmetic starts with the natural numbers and the written symbols (digits) that represent them. The process for combining a pair of these numbers with the four basic operations traditionally relies on memorized results for small values of numbers, including the contents of a multiplication table to assist with multiplication and division.Elementary arithmetic also includes fractions and negative numbers, which can be represented on a number line.
