Matching Circles of Evaluation and Arithmetic Expressions

Directions: Draw a line from each Circle of Evaluation in the left to its corresponding arithmetic expression on the right:

(/ (* 1 1) 1)

$\displaystyle (1 - 1) \;\times\; (1 + 1)$
(/ 1 (* 1 1))

$\displaystyle (1 \;\times\; 1) - (1 + 1)$
(* (- 1 1) (+ 1 1))

$\displaystyle {1 \over 1 \;\times\; 1}$
(- (* 1 1) (+ 1 1))

$\displaystyle {1 \;\times\; 1 \over 1}$
(* (+ 1 (- 1 1)) (+ 1 1))

$\displaystyle (1 + (1 - 1)) \;\times\; (1 + 1)$
