Question

Nd the value of the expression. Type a numerical answer in the space provided. 4 ∙ 1 - 3^2 ÷ 3

Answer 1

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:


`4 * 1-3^2 / 3`

We don't have parentheses, so let's apply second step:


`4 * 1-9 / 3`

Applying third step:


`4-3`

Finally, applying fourth step, the result is:


`1`
