CONSTANTSSkills PageProblem #3Constants are fixed numbers. They never change and remain the same. Generally a constant is a number. However what the number represents determines if that number can change or not. For example:

In example #1 we read that at Costco there are 32 hotdogs per box. That is a constant since every box has 32 hotdogs. That is not going to change unless they get a different size box. So we determine that 32 is constant. Skills PageProblem #2Skills Page Problem #1VARIABLESReturn to Skills PageA variable is something that can vary. Convenient name right. Vary means to change. Something varies because it depends on something else. So a variable in math is a number that can change depending on the circumstances of the question. For example:

In example #1 we read about how the number of hotdogs per person depends on the number of boxes that we buy. We must first answer how many hot dogs per person we decide to give each person, in order to answer how many boxes we are planning to buy.

You decide you want to use 200 dollars to buy a new mp3 player and then use the rest of the money for songs and applications to go on the mp3 player. You make a list of all the games you want and all of the songs you want. Each Application costs 5 dollars and each song costs 1 dollar. How many apps can you get if you bought 50 songs? How many apps can you get if you bought 36 songs? What is more important to you more apps or more songs?

Organize the constants into a mathematical equation (sentence).Return to Skills PageScenario #1Scenario #21001536a1001536a+-x=Equation #1Equation #2x

Organize constants into those that use a mathematical operation(s) to get a total amount and constants that are the total amount. Return to Skills PageConstants
