Описание:
In the 8th grade we learn pre- algebra, which included numbers and letters. At first it was difficult to think of x as a mysterious number but eventually it got easier. This is a good example of FORMALS OPERATIONAL because i gain abstract thinking. I also was a able to plan next semester's classes.Добавлено на ленту времени:
