$2.$ Given the formula:

G $=$ D $+($A $+$ C

$2$

$)\backslash$times E$/($D $+$ B$)$

$3$

show the order in which individual calculations have to be performed to determine the value for G$.$

For example, the value of C

$2$ has to be computed before A $+$ C

$2$ can be computed.

$($a$)$ Break the problem into a sequence of steps, each performing only one calculation, and show

the result of each step $($introduce new letters as needed$).$

$($b$)$ Show which of the steps you identify could be performed at the same time on separate processors, i$.$e$.,$ how you could parallelize this calculation.

$($c$)$ if A $=2,$ B $=4,$ C $=5,$ D $=6$ and E $=8,$ show what the value of G is$.$
