Ilya [14]

Answer:

Option is b is correct answer. Excel performs exponentiation, then multiplication and division, then addition, and subtraction, it is correct order of operation in Excel. It is important to remember when you write any formula in Excel having different mathematical operators like +/ -/ ^/  etc, it follows a specific order and performs calculations in specific order which is termed as order of operator precedence. Each of mathematical operator has its precedence and executes in a special order set by Excel.

Explanation:

  • As we already know order of precedence of each mathematical operator is different in Excel. The order of operations for Excel is as follows:

  • Evaluate elements in parentheses.
  • Evaluate 'ranges' ().  
  • Evaluate 'intersections' (empty spaces).  
  • Evaluate 'unions' (,).
  • Perform negation (-).  
  • determine percentages (%).  
  • Perform exponentiation (^).  
  • Perform multiplication (*) and division (/), both are of equal precedence.  
  • Perform addition (+) and subtraction (-), both are of equal precedence.  
  • Evaluate text operators like (&).  
  • Perform comparisons like (=, <>, <=, >=).

frozen [14]

Answer:

I will code in JAVA.

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

 

boolean tallEnough;

boolean oldEnough;

Scanner input = new Scanner(System.in);

tallEnough = input.nextBoolean();<em> //wait the input for tallEnough</em>

oldEnough = input.nextBoolean(); <em>//wait the input for OldEnough</em>

   if(tallEnough && oldEnough){

   System.out.print(true);

   } else {

   System.out.print(false);

   }

}

}

Explanation:

First, to accept user inputs you have to import the class Scanner. Then declare both variables before allowing the user to set input values for both boolean variables.

In the if-else statement checks if both variables are true, then prints true. Another case prints always false.
