Literal equation
"Dose" is a measured portion of a medicine. A grapheme is a letter or a group of letters that represents a single sound. I I am not aware of any graphemes or grapheme sums that that have measured quantities of medication!
To write an equation, you use symbols and numbers to show a relationship between two or more quantities. The equation typically includes variables, which are represented by letters, and mathematical operations like addition, subtraction, multiplication, and division.
An equation that has several letters or variables is a polynomial
In the equation ( v = u + at ), the letters represent specific quantities related to motion. Here, ( v ) stands for the final velocity of an object, ( u ) is the initial velocity, ( a ) denotes acceleration, and ( t ) represents the time during which the motion occurs. This equation is commonly used in kinematics to describe linear motion with uniform acceleration.
No. The Romans used letters to represent quantities. Whereas the Greeks used letters and symbols to represent quantities.

letters
Letters and symbols are used in equations to represent quantities, sometimes known or unknown. For example the symbol π (pi) represents the constant 3.14… and is unchanging. X or Y in an equation represent unknown terms that may vary depending on the equation, and other variables in the equation. There are numerous examples of both symbols and letters used in mathematical equations, but almost always they are either referring to a known constant term that is more simply expressed as a symbol, or an unknown or general term yet to be concretely determined.
