英语技术说明
Whole numbers only; division always has whole answers. Headings in 11 languages. Everything is calculated in your browser; nothing you type is uploaded.
Problems are drawn at random from your ranges; subtraction swaps numbers when negative answers are off, and division builds the dividend from the divisor so the answer is exact.
Times tables from 2 to 10 give 40 problems in 4 columns, then a second page with the answers.
