To solve the calculation
![3\cdot3+4](https://img.qammunity.org/2023/formulas/mathematics/college/rkq7jsjkhrn9jhgonbvussxuyjweobhvrn.png)
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](https://img.qammunity.org/2023/formulas/mathematics/college/bej7w9fyuj1v3aso1waecl46w24avg5vn5.png)
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}](https://img.qammunity.org/2023/formulas/mathematics/college/jtldotjcr9dlfj79f3gp3qcywf9hjaqygj.png)
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](https://img.qammunity.org/2023/formulas/mathematics/college/fc34ea22ehyb2e6r1h549m45dgm2c1qznu.png)
2) Add both values

So the result of the given calculation is
![3\cdot3+4=13](https://img.qammunity.org/2023/formulas/mathematics/college/7dcpzielwcsnufbodx4q7043nw39lcxmjw.png)
