Equations

Order of operations, solve for n

What your child practices

Using the order of operations (brackets, then × and ÷, then + and −) and solving one-step equations like 6n = 42 with inverse operations, including writing equations for word problems.

Minnesota K-12 Academic Standards benchmark: 6.3.6.4 · solving one-step equations

How we explain it

Children can open this short lesson before they practice.

  1. Follow the order of operations: brackets first.
  2. Then multiply and divide, left to right.
  3. Then add and subtract, left to right.

Example: 4 + 3 × 2 = ? Multiply first: 3 × 2 = 6. Then add: 4 + 6 = 10. Answer: 10

Sample questions

A taste of this unit. In the app, questions change every time and get easier or harder to match your child.

  1. Question 1

    What is 14 + 4 × 3?

    14 + 4 × 3 = ?

    answer box

  2. Question 2

    Maya had some money, spent $12 on a book, and has $6 left. Which equation could find n, the amount Maya started with?

    • n ÷ 12 = 6
    • n − 12 = 6
    • 12n = 6
    • n + 12 = 6

  3. Question 3

    Solve for k.

    k ÷ 9 = 7

    answer box

  4. Question 4

    Solve for y.

    11y = 44

    answer box

  5. Question 5

    A class splits into 3 equal teams with 5 students on each team. How many students are in the class?

    answer box

  6. Question 6

    Which step solves m − 50 = 46 for m?

    m − 50 = 46

    • Multiply both sides by 50
    • Divide both sides by 50
    • Subtract 50 from both sides
    • Add 50 to both sides
