8 ÷ (7 - 9) * ( 4 + (-4) ) <--- notice that bolded part.
4 + (-4) = 4 - 4 = 0.
after that, you're pretty much dividing and multiplying by 0, so
whatever ÷ whatever * whatever * 0 = 0.

Answer:
2 years 5 months
Step-by-step explanation:
TO solve, convert everything to months
1 year has 12 months, so 5 years would have 60, because we multiply by 5.
Then we add the remaining 2 months, 60+2 =62
Then we can convert 2 years to 24 months. Then we add the remaining 9 months to get 24+9, 33
Then we subtract the 2, and get 62-33= 29, and we divide by 12 to convert to years and months. 29 divided by 12 is 2 and 5 months
so your answer is 2 years and 5 months
