Pages
Collecting like terms
Combining like terms, each term carrying the sign in front of it.
Like terms with powers
Why x and x² are unlike terms, and collecting expressions that mix them.
Multiplying terms
Multiplying coefficients and letters separately, so 3a × 4b is 12ab.
Dividing terms
Writing a division as a fraction, then cancelling common factors.
Multiplying powers of a letter
Simplifying 4a³ × 3a² by multiplying coefficients and adding indices.
Dividing powers of a letter
Simplifying 12a⁵ ÷ 4a² by dividing coefficients and subtracting indices.
Raising a term to a power
Applying the index to every factor, so (2a³)⁴ is 16a¹² not 2a¹².
