Interpret the structure of expressions
Grade 912
A.SSE.1.
Interpret expressions that represent a quantity in terms of its context.
A.SSE.1.a.
Interpret parts of an expression, such as terms, factors, and coefficients.
A.SSE.1.b.
Interpret complicated expressions by viewing one or more of their parts as a single entity.
For example, interpret P(1+r)
^{n}
as the product of P and a factor not depending on P.
A.SSE.2.
Use the structure of an expression to identify ways to rewrite it.
For example, see x
^{4}
− y
^{4}
as (x
^{2}
)
^{2}
− (y
^{2}
)
^{2}
, thus recognizing it as a difference of squares that can be factored as (x
^{2}
− y
^{2}
)(x
^{2}
+ y
^{2}
).
