Respuesta :

The ÷ sign is a pretty archaic sign for division. Most people will be using "/".

Anways, what I learned is PEMDAS
Parentheses
Exponents
Multiplication and Division (left to right)
Addition and Subtraction (left to right)

(2− 1) + 3^2 ÷ 3
1 + 3^2 ÷ 3
1 + 9 ÷ 3
1 + 3
4

The answer is D.

Answer:

The answer is D.

Step-by-step explanation:

This question is about pemdas.

P-Parenthesis

E-Exponents

M-Multiply

D-Divide

A-Add

S-Subtract

that came from left to right.

First, calculate with parenthesis.

(2-1)+3²/3

1+3²/3

Then, calculate exponents.

1+3²=3*3=9

1+9/3

Next, divide from left to right.

1+9/3

9/3=3

1+3

Finally add from left to right.

1+3

1+3=4

Final answer: =4

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.
