I'm having trouble defining the recursive method for numbers 4-7 on this assignment. Any help would be greatly appreciated! The programming language is Scheme.

In this assignment, you will be learning Scheme through the use of Dr. Racket. We would like to start with some basic concepts; trying to under prefix notation and the use procedure in Scheme. You will also implement nested procedures and recursive procedures. You may only use the procedures shown in the text and slides - not any of the additional library procedures in Scheme.

4. Define a recursive procedure called "Square" that will compute the square amount of a value by additions. [15 points] 4.1 You must use the Add procedure defined above. 4.2 You will need to account for negative values as well. Hint: This will requjire a conditional and possibly the (abs x) procedure. You may not use multiplication in this procedure definition. Note n2 = 1+3+5+ + (2n-1) (Square 5) 25
