Elementary Arithmetic is an educational App to develop the skill to perform the basic arithmetic operations: Addition, Subtraction, Multiplication, and Division.
There are short drills of 10 or 15 operations, grouped by type and level, so the children will practise according to their knowledge and progression. After each drill the operations not responded correctly will be highlighted.
The multiplication is organised by the times tables, that could be sorted or unsorted.
The main purpose is for children to practice simple arithmetic operations to improve their mental calculations.
