Simplifying in maths means exactly that: making it less complicated, and reducing it to the fewest terms necessary.
not "maths sequences" it's "mathematical sequence" In mathematics, a sequence is an ordered list of objects (or events). Like a set, it contains members (also called elements or terms), and the number of terms (possibly infinite) is called the length of the sequence. Unlike a set, order matters, and the exact same elements can appear multiple times at different positions in the sequence
