A formula is statement written by the user to be calculated. Formulas can be as simple or as complex as the user wants. A formula can contain values, references to cells, defined names, and functions.
All formulas must start with the equals sign.
=1+2+3
A function is a piece of code designed to calculate specific values and are used inside formulas. Functions to sum values, calculate a trigonometric cosine, and to calculate the current time are built into excel. Additional functions can be defined using Visual Basic.
Functions are typed alongside parenthesizes, where in the arguments if any are listed in between. To use functions in a formula, for example
=COS(3.14) will return the calculated cosine.
=NOW() returns the current time.
=SUM(1+2+3) *2 will multiply the sum by 2

A formula as in I=E/R is not compilable but a function written to compute the formula is compilable.
MS Excel is a spreadsheet; MS Paint is a basic graphics editing program.
A nested if.
Syntax is very important when writing Excel formulas. Each formula and function will help guide you through how to format the equation. Probably the most important thing to remember about syntax is to begin all formulas with the equal sign, or Excel will just interpret your entry as text and not calculate anything.EXAMPLE: =SUM(A1:A12) [Adds the contents of cells A1 through A2]
I don't believe that Excel has such a function; you'll have to write one yourself.
It's possible that Excel was written in C.
