In the expression ''I will answer after I have received the the letter" the speaker is saying that they have not received the letter yet, but when they do, or rather, after they receive it, they will answer (something). The whole matter is in the future.
But if someone says "After I received the letter..." they have already received the letter and then did something. It all happened in the past.
The expressions...(1) ''I will answer after I have received the letter", and(2) "I will answer after I receive the letter"... both mean the same thing.The only difference is the choice of verb form. The first sentence uses the 'Present Perfect with future meaning'. The second sentence uses the the 'Present Simple for the future.'In some situations the choice between the two verb forms is important, but in this particular case the meaning is clear and unambiguous, whichever style of speech the speaker uses.

If you are asking what is the difference between ending a word in the English language with the letter s and with an apostrophe mark before the s, as this 's, it is the difference between making a word plural and making a word possessive. For example mother can be made to mean more than one mother by adding the letter s to make it mothers. There were several mothers who attended the school meeting. When you place an apostrophe mark before the letter s, you are indicating that the word you have printed, written, or typed, owns something or something belongs to the thing that that word represents. For example, That book is my mother's. (book). This is a simplistic answer, but I think it is adequate for now.
The main difference between long "i" and short "i" is the duration of the sound. Long "i" is pronounced for a longer period of time, as in words like "time" or "ride." Short "i" is pronounced for a shorter period of time, as in words like "sit" or "big."
A variable is a single letter that represents a number. For example x is a variable.An algebraic expression can contain variables, numbers, mathematical symbols, etcetera. An example of an algebraic expression is 3x+12.
n - 8 is the expression for the difference of eight and a number.'Number' is a variable, so the variable must be a letter (in this case, 'n'). 'The difference' is going to be the subtraction symbol that is in between the 'number' and eight, so it must be n - 8. It could, of course, be 8 - n.

Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.
The difference is a letter L.
