Tilly counts 120 stars to the east of her house and six times that number to the west. How many stars does she count total?
First find the total number of stars she saw in the west: 120 stars * 6 = <<120*6=720>>720 stars
Then add the number she saw in the east to find the total number: 720 stars + 120 stars = <<720+120=840>>840 stars
#### 840
