"Mathematics is a part of everyday life and can be used in every aspect of
life..." A re-occurring phrase that echos in classrooms across the world... But
how can we prove to students that math can be applied to everyday life? Surely,
there are math problems they will never see in life again. However, whether or
not students will experience deja vu when completing math problems is not the
point. Educators emphasize the importance of mathematics because the technique
used to solve problems in mathematics is in fact something students can carry
with them for the rest of their lives.

Coin Word Problem
Your best friend walks into a bar, jingling coins in his pocket. He grins at you and tells you that you can have all the coins if you can figure out how many of
each kind of coin he is carrying. You’re uninterested, until he tells you the coins add up to seventeen dollars. He tells you there are twenty six coins, which consist only of silver dollars and quarters. How many of each coin does he have?

This problem combines a number of different concepts within Algebra. Not only do we use variables to solve the problem, but also we need to understand how to use expressions and equations (and how they differ). Additionally, ideas such as PEMDAS and combining like terms are utilized. Students can use this problem to become familiarized with these mathematical concepts. Furthermore, the coin problem is real world applicable, so we can see a direct connection between the topic and real life.

SEVEN bridges of konigsberg
The old town of Königsberg has seven bridges: Can you take a walk through the town, visiting each part of the town and crossing each bridge only once?
