Question

write a program to perform mathematical operation addition subtraction multiplication division on the given numbers and operator plus minus divide asterisk will be inputted by the users ​

Answer 1

Answer:

from numpy import *

lst = [ ]

o = input('Enter operation name (Addition, Subtraction, Multiplication, Division): ')

   o = o.strip()

   o = o.lower()

   if o == 'addition':

       c = int(input('How many numbers do you want to add? '))

       for i in range(c):

           num = int(input('Enter a number: '))

           sum+=num

       print('The sum is: ', sum)

   elif o == 'subtraction':

       s1 = int(input('Enter 1st number: '))

       s2 = int(input('Enter 2nd number: '))

       print('Difference between', s1, 'and', s2, 'is', s1-s2)

   elif o == 'multiplication':

       x = int(input('How many numbers do you want to multiply? '))

       for i in range(x):

           n = int(input('Enter a number: '))

           lst.append(n)

       for i in range(len(lst)):

           arr = array(lst)

       print('Product of all numbers is: ', prod(arr))

   elif o == 'division':

       d1 = int(input('Enter 1st number: '))

       d2 = int(input('Enter 2nd number: '))

       print('Quotient of numbers is: ', d1/d2)

For this you should install Python package Numpy!!

Hope it helps!!

Answer 2

Explanation:

import java.util.Scanner

class show

{

public static void main (String args[ ])

{

int a , b , c

System.out.println (" Enter your number ");

a = next.Int();

System.out.println ("Enter your number ");

b = next.Int();

c = a+b;

System.out.println ("Here is your added number"+c);

}

}
