Could someone walk me step-by-step through these Order of Operation questions I got wrong in a quiz?

Question

1. (3)(4)+(8)(5)+16 ÷2 x 4

2. (6)(5)+(2)(8)+14 ÷2 x 7

(Please explain in a middle school level way)

I know the PEMDAS, and I got 54 and 47, but my teacher marked it wrong... -_-

Answer 1

PEMDAS
Parenthesis Exponents Multiplication Division Addition Subtraction
1. (3)(4)+(8)(5)+16÷2x4 Multiply
12 + 40 +16 ÷ 8 Divide
12+40+2 add
54
2.(6)(5)+(2)(8)+14 ÷2 x 7 Multiply
30+16+14 ÷14 Divide
30+16+1 Add
47

Answer 2

you do 16 divided by 2 ( u do division first
(3)(4) + (8) (5) +16 divided by 2times 4
(3) (4) + (8) (5) +* times 4
12 + 40 times 4
12 +160=
172
the order of operations (first to last) goes divide, multiply, subtract, add
if you have multiple of these operations like the problem above you do it by which one is first
number 2
(6) (5) + (2) (8) +14divided by 2 times 7
(6) (5) + (2) (8) +7 times 7
30 + 16 +49=95
