💡 Need a quick reminder? Click here for Rules & Tips

Use negative numbers in context and calculate intervals across zero.
Don’t include any symbols.

🙂 = Correct, ☹️ = Incorrect

📌 Rules

• Negative numbers are numbers less than zero, and they get smaller the further below zero they go.

• When counting backwards through zero, the order goes 3, 2, 1, 0, -1, -2, -3.

• To find the difference between a positive and a negative number, add their distances from zero together.

💡 Tips

• Draw a vertical or horizontal number line with zero in the middle to help you count steps accurately.

• Think of real-life examples like temperature (below freezing) or floors in a building below ground level.

• Our platform keeps typing quick and simple by using plain digits only, so there is no need to add any spaces or commas when typing your answers.

⚠️ Warnings

• Remember that -10 is smaller than -2 because it is further below zero.

• Take extra care when crossing zero so you do not forget to count zero as a step on the number line.

What number on the number line is the arrow pointing to?

Need help? NoYes

Establish the value of one interval (step) on the number line, then count the steps between zero and the arrow. If 1 step = 1, then the value of 3 steps from zero to the left will be -3 and the value of 3 steps to the right will be 3.
