Question: Evie is collecting seashells while at the beach. Each day she collects her favorite 10 shells. At the end of 6 days, she gives 2 shells to her brother. How many shells does she have left?
Answer with step-by-step thinking:
Multiply the number of shells collected each day by 6, to get the total number of seashells Evie has collected: 10 x 6 = 60 seashells. Subtract the 2 shells she gave her brother, to get the number of shells she has left: 60 - 2 = 58 seashells.
So the answer is 58.
