# Change the order of mathematical evaluation

Here we have a mathematical calculation involving 3 variables. Change the order of mathematical evaluations such that the subtraction is calculated first. Use parentheses to do so. The result should be 30.

```
a = 5
b = 10
c = 4
```

```
result = a * b - c
```

```
# result should be 30
print(result)
```
