This is a problem of Arithmetic that is a branch of mathematics that consists of the study of numbers. Its main goal is the study of the traditional operations on them just as: addition, subtraction, multiplication and division. There is an order of operation to solve problems in arithmetic that is the way you choose to simplify expressions. This order is like this:
1. First. Solve Parentheses.
2. Second. Solve Exponents (and root).
3. Third. Solve Multiplication and Division
3. Fourth. Solve addition and subtraction.
So let's apply these concepts to our problem:
[tex]4 \times 1-3^2 \div 3[/tex]
We don't have parentheses, so let's apply second step:
[tex]4 \times 1-9 \div 3[/tex]
Applying third step:
[tex]4-3[/tex]
Finally, applying fourth step, the result is:
[tex]1[/tex]
