Final answer:
The concept of using specific units to refer to numbers of items, such as 'six-pack' or 'dozen,' is commonplace in both mathematics and daily life, and extends to items like creams where a 'finger tip unit' may be used.
Step-by-step explanation:
The question 'specific number ordered (ex. 3 cream)' in context appears to be related to the concept of using units to refer to specific numbers of items. This concept is common in both everyday life and mathematical contexts when quantifying and discussing items.
For example, six-pack when referring to cans of soda, dozen for eggs, and ream for sheets of printer paper. In a scientific context, chemists use the mole to represent Avogadro's number, which is 6.022 x 1023 items, typically used to count atoms, molecules, or ions due to their minuscule size.
In the case of creams, a topical application used for the skin, an important unit is the finger tip unit, which helps in determining the amount of cream needed to cover specific areas of the body, merging the concept of quantity with medicine and pharmacology.
