Answer:
The numerical expression is simplified into 8.
Step-by-step explanation:
You have to use the P.E.M.D.A.S. formula.
16-8[(3+6)÷9]
Solve the brackets(parenthesis) first.
Inside the brackets, you have to use the P.E.M.D.A.S. formula once again, as if it was a different equation.
16-8[(9)÷9]
Once you've found the solution to the equation 3+6 inside the parenthesis, you divide it by 9.
16-8[1]
Then, since there are no exponents, you multiply.
16-8
Then you subtract.
8
No, because 9/3=3 but 7.3/3=2.433..... And not 2.2
X= -18 (negative eighteen)
