Use PEMDAS
Parenthasis
Exponents
Multiplication/Division (whichever comes first)
Addition/subtraction(whichever comes first)
First do whats in Perenthasis
16-9 is 7
now we have
18 + (7) ·4
Multiplication comes next in PEMDAS
do 7 x 4. Youll get 28
Now we have 18 + 28
Add them to get 46
The final answer is 46 :)
