## Exercise 1*



### 1.
$num_{BS}:$ $5 \to 5$ $num_{BS}:$ $8 \to 8$
$mult_{BS}:$ $5 * 8 \to 40$
$num_{BS}:$ $4 \to 4$ $par_{BS}:$ $(5 * 8) \to 40$
$num_{BS}:$ $3 \to 3, 12 \to 12$ $par_{BS}:$ $4 * (5 * 8) \to 160$
$plus_{BS}:$ $3+12 \to 15$ $mult_{BS}:$ $4 * (5 * 8) \to 160$
$par_{BS}:$ $(3+12) \to 15$ $par_{BS}:$ $(4 * (5 * 8)) \to 160$
$mult_{BS}:$ $(3+12) * (4 * (5 * 8)) \to 2400$

## Exercise 3*
$\frac{a_1 \to_{exp} v_1}{a_1=a_2 \to a_1' = a_2}$
