In algebra, we find not just answers, but methods eternal.

Hindu numerals liberate the mind from cumbersome symbols.

To complete and balance is the essence of algebraic art.

As I near the end, I see mathematics as the true legacy of the soul.

When I considered what most people generally want in calculating, I found that it was always a number.

I have discovered that these numbers are used in all calculations, and they are the foundation of all arithmetic.

What is easy to understand and grasp, and what is most useful in all calculations, is the method of 'al-jabr' and 'al-muqabala'.

This book contains the rules of algebra, which are the most noble and useful of all mathematical sciences.

The science of algebra is a science of great utility, and it is the foundation of all other sciences.

I have composed this book on calculation by completion and balancing, which is a concise and easy method for solving all kinds of problems.

The rules of algebra are necessary for all those who wish to understand the principles of arithmetic and geometry.

This book is intended for those who are interested in the science of numbers and their applications.

The method of 'al-jabr' is to restore the balance by adding the same quantity to both sides of an equation.

The method of 'al-muqabala' is to cancel out equal terms on both sides of an equation.

These two operations, 'al-jabr' and 'al-muqabala', are the foundation of all algebraic calculations.

I have explained these rules with clear examples, so that they may be easily understood by all.

The science of algebra is a noble and useful science, and it is the key to understanding many other sciences.

This book is a guide for those who wish to master the art of calculation.

The rules of algebra are essential for solving problems in geometry, astronomy, and other sciences.

I have presented these rules in a clear and concise manner, so that they may be easily applied to various problems.
