be sure you take a single step at a time, and name what rules/operations are used to do so. (We'll relax that a bit on test days). 1.3.1 expressions to reduce: ((x. x + x) 3) (((a. b. if (a > b) a b) (3*4)) (1+2)) ((x. y. x*(x-y)) 100) (x. y. (x*(x-y+3))) (((f. n. f n) (x.3*x)) 7) (((x. if (x<5) (f.f x) (g.g 5)) 5) (s. s*s)) ((x. if x true false) 5)
