To solve the calculation
[tex]3\cdot3+4[/tex]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:
[tex]3\cdot2\cdot4[/tex]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.
[tex]\begin{gathered} 3\cdot2\cdot4=6\cdot4=24 \\ \end{gathered}[/tex]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
[tex]3\cdot3+4=9+4[/tex]2) Add both values
[tex]9+4=13[/tex]So the result of the given calculation is
[tex]3\cdot3+4=13[/tex]
