THE FIELD NOTES
How to play Number Rush
- Read the question carefully: it may ask for a result, a missing value, or an operator. Do not assume the next question uses the same rule.
- Type a whole-number answer when an input appears, or choose from the options when the question offers them.
- Check the explanation after answering in solo play. Untimed practice lets you work through the method before trying a sprint.
A worked example
In 7 + ? = 12, subtract seven from twelve to find five. If the question instead asks which operator makes 7 ? 5 = 12 true, choose addition rather than entering a number.
A strategy to try
Estimate the size of the answer before calculating. Then work backwards to check it: putting your answer into the original question should make the relationship true.
Choose your challenge
Five levels change the arithmetic and reasoning demands. A younger starting suggestion selects untimed collection play, and you can change the level yourself.
Each round has ten questions. Choose a 90-second sprint or untimed practice. Correct answers earn 100 points; finishing a sprint adds up to 99 time-bonus points. A score describes this round, not intelligence or a medical assessment.
