Note: " (8 * 4) + 90 ÷ 9 " = " (8 * 4) + (90 ÷ 9) " = "32 + 10 = 42" .
We can rewrite the "fraction":
7 / [ (8 * 4) + 90 ÷ 9 ] ; as:
;
and can reduce this value to (and rewrite as): "
" ;
{ since: " = 
= " .}.
Note: The "fraction" :
; the "9/6" cancel to "3/2" ;
{Since: "9÷3 = 3" ; and since: "6÷3 = 2" ).
So rewrite: ; as:

So, we can rewrite our expression as:
÷ * ;
_________________________________________________________
Note:
_________________________________________________________
÷ * ;
= ( ÷ ) * ;
= ( * 
) * ;

Start with :
________________________________________________________
→ ( * ) ;
The "6" in the " " ; cancels to a "1" ;
and the "6⁴ " in the " ) " ; cancels to a "6³ " ;
→ {Since: "6⁴ / 6 = 6⁴ / 6¹ = 6⁽⁴ ⁻ ¹⁾ = 6³ ;
→ and we have:
* 
;
→ The " " can be eliminated; since "1÷1= 1 " ;
and since: any value, divided by "1", equal that same value; & since "any value, multiplied by "1"; equals that same value" ;
________________________________________________________
We have: " 6³ " .

Now, we multiplied this value, " 6³ " , by " " ;
→ 6³ * ;
= * ;
Note: The "6³ " cancels out to "6² " ; and the "6" cancels out to "1" ;
{since: "6³ ÷ 6 = 6³ ÷ 6¹ = 6⁽³ ⁻ ¹⁾ = 6² " ;
and since: "6 ÷ 6 = 1 " ; ________________________________________________________
→ The answer is: 6² = 6 * 6 = 36 ;
