Okay thank goodness for everyone

Keep in mind PEMDAS(the order of which you solve it is, parenthesis, exponent, multiplication, division, addition, subtraction!)

Start with P(Parenthesis)

A)Well 6+5=11 and 4-1= 3 so 11×3=33

B)12-3=9(here

Where a lot of mistakes happen, you need to keep PEMPAS in mind, D is before A so you need to divid 18/9 before adding 5) so now it is

2+5=7!

C)12+20=32 and 9×2=18 and 18-2=16

Now now the problem is

32/16 which you know is 2!

D)5.2+3.4=8.6 and 8.6×1.5=12.9 which is your answer!

E)6.7-2.7=9.4 and 8.2/9.4=.87

F)2.7+3.1=5.8 and 9.5-5.8=3.7!

These are my personal answers of which were a tad bit rushed through so I would double check and take it with a grain is salt but I hope that this helps!
