Данное пособие включает в себя все возможные комбинации однозначных и двузначных чисел на уровне «ПРОСТО» (сложение и вычитание). В сборнике представлено более 700 примеров (5 вариантов), распределенных по разделам в соответствии с составами чисел. В каждом варианте 13 разделов (от однозначных чисел: 1 – 5 до двузначных: 90+, +90).

Решебник придназначен для решения примеров по ментальной арифметике на уровне «ПРОСТО» на абакусе и ментально. Рекомендуется использовать как для самостоятельной отработки полученных навыков счета, так и при подготовке к занятиям и контрольным работам по ментальной арифметике.
