Expanding Brackets: Use the distributive law to eliminate brackets by multiplying each term inside by the term outside. For example, 2(3 + x) expands to 6 + 2x.

Collecting Like Terms: Combine terms that have the same variable by adding or subtracting their coefficients. For example, -5x + 2x simplifies to -3x.

Handling Negative Signs in Brackets: When a negative sign is in front of brackets, treat it as multiplying by -1 to reverse the signs of all terms inside the brackets.
