Oral arithmetic practice problems such as addition, subtraction, multiplication and division can be randomly generated, and typeset as A4 paper images for direct printing. You can freely set whether the arithmetic includes addition, subtraction, multiplication, division and parentheses, as well as the range of values of the arithmetic and the result, and you can set the number of rows, columns, titles, fonts and margins of the exercise questions. Practice questions and answers can be saved separately so that you can check the exercise results.
