Problem:

Given two integers, X and Y, find their sum, difference, product, and quotient.

# Input

5
2

# Output

7
3
10
2

# Solution

            
    read a
    read b

    echo "$((a + b))"
    echo "$((a - b))"
    echo "$((a * b))"
    echo "$((a / b))"

# Solution_01

            
    read a
    read b
  
    echo "$[a+b]"
    echo "$[a-b]"
    echo "$[a*b]"
    echo "$[a/b]"

# Solution_02

            
    read a
    read b
  
    echo `expr $a + $b`
    echo `expr $a - $b`
    echo `expr $a \* $b`
    echo `expr $a / $b`

# Solution_03

            
    read a
    read b
  
    echo `expr $a + $b`
    echo `expr $a - $b`
    echo `expr $a \* $b`
    echo `expr $a / $b`

# Solution_04

        
  read X
  read Y
  
    for op in '+' '-' '*' '/'
    do
        echo "$X $op $Y" | bc
    done
