Negative numbers finally make sense. Negative Numbers is a colourful maths game that teaches kids how numbers below zero really work — one friendly level at a time. No walls of text, no pressure. Just a cheerful penguin, a number line you can actually drag, and 100 levels that build real confidence. DRAG THE NUMBER LINE Every adding and subtracting question comes with a number line you can play with. Slide the ball left and right, watch the value change as you count, and see for yourself why −4 + (−2) lands on −6. It is a scratchpad, not a test — moving it never costs you points. 100 LEVELS ACROSS 8 WORLDS The course grows with your child, one skill at a time: • Below Zero — meet the minus and add negatives • Going Down — subtracting, and why two minuses make a plus • Mix & Match — plus and minus in the same puzzle • Sign Factory — multiplying with signs • Split the Sign — dividing with signs • Power Up — square numbers, and the bracket trap • Root Cave — square roots • Grand Master — everything, all at once LEARN FROM EVERY ANSWER Each level opens with a short lesson card and a worked example. Get a question wrong and nothing is lost — the game explains the mistake in plain language and lets you try again. Three questions clear a level, and a flawless run earns three stars.
