Structure first, then calculation

In an expression with monomials, rules are not applied simply in the order they appear. Resolve parentheses first, then powers, then multiplication and division from left to right; only afterwards combine additions and subtractions of similar monomials.

Formula matematica

First 2x²·4 = 8x²; then 3x² + 8x² = 11x².

Formula matematica

Resolve the parentheses first: 3x². Then 3x²·3x = 9x³.

Operation order

1) parentheses → 2) powers → 3) products and quotients from left to right → 4) addition and subtraction of similar terms.

In exercises containing a variable in the divisor, that variable is assumed to be non-zero, as is standard in school-level monomial division.

What you need to know before the exercises

In this lesson: Plan and simplify mixed monomial expressions while respecting precedence, parentheses and normal form.

Guide

Do not calculate everything at once. First identify the next operation required by the hierarchy, perform it, normalize the intermediate result, and continue.

Formula matematica

Write the result using ordinary mathematical notation, as you would on paper.
