Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.
Question 1
What is 6n + 2n?
6n + 2n
- 12n
- 8
- 8n
Show answer
8n
Hint: Add the numbers in front. The letter stays the same, like adding apples to apples.
Question 2
What is 2y + y?
2y + y
- 2y²
- 3
- 3y
Show answer
3y
Hint: y means 1y. So add 2 + 1.
Question 3
Evaluate 6n − 2 when n = 6.
6n − 2, n = 6
answer box
Show answer
34
Hint: Put 6 in for n. Multiply first, then subtract.
Question 4
Which shows the solution to n > 7 on a number line?
- a closed circle at 7 with an arrow pointing right
- an open circle at 7 with an arrow pointing right
- an open circle at 7 with an arrow pointing left
Show answer
an open circle at 7 with an arrow pointing right
Hint: An open circle means the number itself is not included. The arrow points to the numbers that work.
Question 5
Evaluate 6n + 8 when n = 3.9.
6n + 8, n = 3.9
answer box
Show answer
31.4
Hint: Put 3.9 in for n. Multiply first, then add.
Question 6
Which shows the solution to n < 8 on a number line?
- an open circle at 8 with an arrow pointing left
- a closed circle at 8 with an arrow pointing left
- an open circle at 8 with an arrow pointing right
Show answer
an open circle at 8 with an arrow pointing left
Hint: An open circle means the number itself is not included. The arrow points to the numbers that work.
