Simplifying rewrites an expression into an equivalent form that is easier to read or work with. Typical moves include combining like terms, folding constant arithmetic, and removing redundant factors.

For example, $2x + x + 6$ simplifies to $3x + 6$.

Use * for multiplication, ^ for powers, and parentheses when grouping terms matters. Variables like x, y, and t are supported.

If the result matches the input, the expression may already be in a compact equivalent form.
