Cheryl ate 7 m&m's after lunch. She ate 5 m&m's after dinner, and she gave some to her sister. If Cheryl had 25 m&m's at the beginning, how many did she give to her sister?

How many m&m's did Cheryl eat after lunch and dinner? ** Cheryl at 7 + 5 = <<7+5=12>>12 m&m's
How many m&m's did Cheryl give to her sister? ** She gave 25 - 12 = <<25-12=13>>13 m&m's to her sister.
