Question

3 * 3 what is 3 * 3 + 4

Answer 1

To solve the calculation

`3\cdot3+4`

You have to pay attention to the order of operations.

Operations follow always the same order:

1. Parentheses

2. Exponents

3. Multiplication/ Division

4. Addition/ Subtraction

And the direction you have to solve them is always from left to right, so if you, for example, have to multiply three numbers:

`3\cdot2\cdot4`

Is the same operation, so you have to solve it from left to right, that means, multiply the first two digits first, and then multiply the result by the third digit.

`\begin{gathered} 3\cdot2\cdot4=6\cdot4=24 \\ \end{gathered}`

For the given calculation you have a multiplication "3*3" and then addition. Following the order of operations, you have to solve the multiplication first, and then the addition as follows:

1) Multiply 3*3

`3\cdot3+4=9+4`

2) Add both values

`9+4=13`

So the result of the given calculation is

`3\cdot3+4=13`
