when you enter a formula in a cell the result of the calculation displays in a cell. how do views of formula after entering it?
Vika [28.1K]

<u>Answer:</u>

Any formula entered in the excel sheet should begin with “=”. Otherwise excel reads that to be a normal text and it will not process the further to get a “result”.

A formula can be entered either in <em>the cell or in the “formula bar”</em>. Once a formula is entered and an enter key is encountered, the result will be displayed in the <em>cell and connected formula</em> gets displayed in the Formula bar.

When we move the focus over that cell it <em>displays only content and not formula,</em> because formula gets displayed only in the “formula bar”.

Write a Scheme function called "sum" which takes an input function func and a nonnegative number n and outputs the value
solong [7]

Answer:

function sum(number) {

      if (number == 1) {

             return 1;

      }

      return number + sum(number -1);

}

Explanation:

This is a recursive function, it means that is a function that calls itself for example: if you call the function with sum(5) the process is :

sum(5)

   |______ 5 + sum(4)

                           |_______ 4 + sum(3)

                                                       |______ 3 + sum(2)

                                                                                   |_____2 + sum(1)

                                                                                                        |_____ 1

                                                                                                 

the result is 1+2+3+4+5 = 15
