What is subtraction?
To subtract in mathematics is to take something away from a group or a number of objects.
In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.
The group's total number of items decreases or becomes lower when we subtract from it.
Number of tokens she won = 11
Number of tokens she spent= 15
Number of tokens she buy = Number of tokens she spent - Number of tokens she won
Number of tokens she buy = 15 - 11 = 4
Hence "She buys 4 games tokens during playing games".
