Master addition and subtraction of large numbers

This book (PDF) contains more than 100 pages of printable exercises. Just like the others
books, we try to offer a simple tool so that the child can, on his own, carry out the exercises and check his answers using the answer key.
The minimum knowledge required to fully benefit from this book is to know the numbers up to 100 and to know how to add and subtract single-digit numbers.
This book focuses on the exercises and the answer key without explanation. So the child will find hundreds of equations at each level of addition and subtraction from  2-digit numbers without swapping like (47-32=15) and (56+21=77) up 4-digit numbers with swap like (2257+3079=5336) and (7627-4728=2899). The book contains six levels. Generally, the book can be useful for
children from 7 to 10 years old.
