Order of operations W1-mt_jHgRQ4hR0g-s1

  1. False · You can't just work left to right. Multiplication comes before addition.
  2. 18 · Multiplication happens before addition, so you multiply first.
  3. 2 × 4 · Multiplication comes before addition, so you solve 2 × 4 first.
  4. False · It's the other way around: multiplication and division come before addition and subtraction.
  5. 8 · Multiply before you subtract or add, then go left to right.
  6. 12 · Do division and multiplication before addition, working left to right.
  7. Multiplication (2 × 5) · Order of operations puts multiplication ahead of addition.
  8. 17 · Multiply first: 3 × 4 = 12. Then add: 12 + 5 = 17.
  9. 20 · Multiply first: 4 × 3 = 12. Then add: 8 + 12 = 20, not 36.
  10. 22 · Do both multiplications before you add them together.
