As long as there is no time or divided, you can easily count from right to left.
For example 17+17-10=_
17+17=34 34-10=24 Solution of the task is therefore 24.

If the invoice is once or divided, it must be calculated first.
for example 60+17-2*5=_
first count the paint task: 2*5=10
60+17-10=__ here as above calculate from left to right: 60+17=77 77-10=67 Solution of the task is 67

If you can use a mobile phone, you can also use a calculator.

Much success in the implementation.
