Q$2.$ Consider this formula:

$()()$

$32$ G D A C $*$E $/$ D B $=+++$

a$.$ Show the order that a processor would follow to calculate G$.$ To do so$,$ break down

the equation into the correct order of operations with one calculation per step. Show

the formula for each step, assigning new letters to calculations as necessary.

b$.$ Find the value of G: if A $=2,$ B $=4,$ C $=5,$ D $=6,$ and E $=8.$
