Write the following using literals, numbers and signs of basic operations:
I) The product of x and y added to their sum
II) 5 times b added to 3 times c
III) Twice x added to y square.

Dear Student,

1) Product of x and y = xy
    Sum of x and y = x + y
So, Required expression = x + y + xy

2) Required expression = 5b + 3c

3)  Required expression = 2x + y2
