Apply the rules for order of operations to simplify (2 - 1) + 3² ÷ 3.

Solution:

Given, (2 - 1) + 3² ÷ 3

We have to simplify the expression by applying the rules for the order of operations.

By using PEMDAS,

P - Parenthesis

E - Exponents

M- Multiply

D - Division

A - Add

S - Subtract

From left to right.

a) first simplifying (2-1) = 1

b) next simplify, (2-1) + 3² = 1+9

c) now, (2-1) + 3² ÷ 3 = 1 + 9/3

= 1 + 3

= 4

Therefore, the simplified form of the given expression is 4.
