📖Subtraction Fluency

By grade 6, you should be able to subtract large numbers quickly and accurately. The key is to be systematic: always work from right to left, regroup when needed, and double-check your work.

💡

For very large numbers, break the problem into smaller parts mentally. Think of 8,742 - 3,526 as (8,000 - 3,000) + (742 - 526) if no regrouping is needed between thousands and hundreds.
