Mixed grade 4 arithmetic
This trainer combines large numbers, written methods, rules, units, rounding, and missing-number tasks.
How to solve this
- Read the task type first: a unit comparison, a rounding task, and a missing factor need different strategies.
- Estimate before calculating so you know whether the answer is in the right size range.
- After solving, check with the inverse operation, the original unit, or the rounded estimate.
Examples
12,000 × 3
36,000
48,230 rounded to the nearest thousand
