For Max Points Possible, be sure to validate user input as per the techniques discussed in class, or as per another manner.

$1.$Create a Folder on your saving location called $$Unit$2\_$Calculator$\_$YourLastName$$ to hold all files of this project

$2.$ Create a $.$cs$$called$$Calculator$\_$YourLastName.cs

$3.$ Implement a calculator based upon the following algorithm: $$

first number $=$ get input from user

if first number not numeric then print warning

second number $=$ get input from user

if second number not numeric then print warning

operation $=$ get input from user

lower case the operation for case insensitivity

if operation is $+$ or "add" then

$$ print first number $+$ second number

otherwise$$if$$operation$$is $-$ or "subtract" then

$$ print first number $-$ second number

otherwise$$if$$operation$$is $*$ or "multiply" then

$$ print first number $*$ second number

otherwise$$if$$operation$$is $/$ or "divide" then

$$ print first number $/$ second number

otherwise

$$ print warning

Sample input$/$output

Number$1$: $3$

Number$2$: $5$

Operation: $+$

$=8$

OR

$$

Number$1$: $3$

Number$2$: $5$

Operation:$$add

$=8$

Consider my code example here:
