/ Dates of Notes/ Activities
Limits to an equation’s solution are indicate with words such as “maximum” and “minimum” /
Symbols are used in an equation to represent unknowns and operations. A variable is a symbol that represents and unknown amount /
An equal sign means that something is balanced, not that both sides are the exact same, but that they have the same value /
A constant is a value that does not change /
A constant and a variable placed next to each other represent the “hidden” operation of multiplication /
How to simplify expressions, and recognize equivalent expressions /
Vocabulary that represents the different mathematical operations /
