Answer:
24
Explanation:
The most important thing to note here is that there are no parentheses defining what to do when.
Therefore, we have to use order of operations - PEMDAS, to find the expression's value.
PEMDAS states that the order you go in is:
1. Parentheses
2. Exponents
3. Multiplication/Division
4. Addition/Subtraction

There are no parentheses, so first we have to solve the exponent.
![6^2=36\\\\36-3\cdot4](https://img.qammunity.org/2021/formulas/mathematics/college/9jh5d989w5yfltbuvuvdaz2o5d5yknizx8.png)
Now we have to multiply.

And now subtract.
