What are Arithmetic operations?
Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
Alex's first 10 all hit the target and earned him 20 more.
Now he has 20 and has used 10.
His next 5 hit the target and earned him 10 more.
He now has 25 (20–5+10) and has used 15.
All of the remaining 25 miss the target.
Alex had used a total of 40 arrows (25+15) and has hit the target 15 times.
