2. Clearing denominators - Wikipedia

   en.wikipedia.org/wiki/Clearing_denominators

   The first step is to determine a common denominator D of these fractions – preferably the least common denominator, which is the least common multiple of the Q i. This means that each Q i is a factor of D, so D = R i Q i for some expression R i that is not a fraction. Then

3. Number bond - Wikipedia

   en.wikipedia.org/wiki/Number_bond

   In mathematics education at primary school level, a number bond (sometimes alternatively called an addition fact) is a simple addition sum which has become so familiar that a child can recognise it and complete it almost instantly, with recall as automatic as that of an entry from a multiplication table in multiplication.

4. Lattice multiplication - Wikipedia

   To find the position of the decimal point in the final answer, one can draw a vertical line from the decimal point in 5.8, and a horizontal line from the decimal point in 2.13. (See picture for Step 4.) The grid diagonal through the intersection of these two lines then determines the position of the decimal point in the result. [2]

5. Slide rule - Wikipedia

   en.wikipedia.org/wiki/Slide_rule

   The user may estimate the location of the decimal point in the result by mentally interpolating between labeled graduations. Scientific notation is used to track the decimal point for more precise calculations. Addition and subtraction steps in a calculation are generally done mentally or on paper, not on the slide rule.

7. Fraction - Wikipedia

   en.wikipedia.org/wiki/Fraction

   Decimal fractions are commonly expressed using decimal notation in which the implied denominator is determined by the number of digits to the right of a decimal separator, the appearance of which (e.g., a period, an interpunct (·), a comma) depends on the locale (for examples, see Decimal separator). Thus, for 0.75 the numerator is 75 and the ...
