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.

The exact question to solve is down below, example on how to solve it

ex: 3 + 5 - 7 ( (- (+ 3 5) 7)) <------- This is what i am looking for

1. Using Dr. Racket to compute the following expressions. [5 points] 1.1 19 * 12 + 25 - 33 1.2 15 * ( 16 + 5 / 3 ) - 12 * 7 1.3 121 * (( 15 - ( 4 * 3 )) + ( 19 / 4 ) ) * 14 1.4 (22 + 33) * ( 21 + ( ( ( 15 / 6 ) + ( 3 * 4 ) ) / ( 5 - 7 ) ) ) 1.5 ( ( ( ( ( ( 6 - 9 ) * ( 11 * 5 + 7 ) ) / 2 ) / 2 ) 5 ) / 3 ) + ( ( ( ( 7 * 5 ) + ( 8 / 2 * 4 ) ) / 2 ) + ( 9 * 5 ) )
