    Question: Emily is baking cookies. She arranges the cookie dough blobs on a baking sheet in 7 rows. Every even numbered row has 7 cookies, and every odd row has 8. How many cookies does Emily bake?

     

    Solution: The even rows—the 2nd, 4th, and 6th rows—each have 7 cookies. Three rows of 7 cookies have 7 × 3 = 21 cookies. The odd rows—the 1st, 3rd, 5th, and 7th rows—each have 8 cookies. Four rows of 8 cookies have 8 × 4 = 32 cookies. That makes 21 + 32 = 53 cookies in total.

    Before I came to Mathnasium, I could sum up everything I felt about math in one word: 'EVIL!' I hated math. ... Mathnasium has been my safe haven. They truly have shown me the light when it came to addressing my fear and provided me with the tools that I need to rebuild my prior knowledge so that I won't forget it. Math is no longer a subject I shy away from but it is a subject I can boldly accept and understand.
