INSERT INTO .... inserts records into a table.
Have a go at this exercise:
insert into car_sales(make,model,purchase_price,purchase_date,sold_price,sold_date,carname)
values('porscheeeee','911',100678,'20190419',110321,'20200117','porsche 911')
insert into car_sales(make,model,purchase_price,purchase_date,sold_price,sold_date,carname)

EXAM TIP: INSERT INTO is certainly one of the more simpler statements. There is not much space for ambiguity really. Make sure you learn it, as it is a part of the AQA spec.
