 WHAT is ALGEBRA?
Algebra is named in honor of Mohammed ibn Musa al-Khowârizmî. Around +825,
he wrote a book entitled Hisb al-jabr wa'l muqubalah, ("the science of reduction and cancellation"). His book, Al-jabr,
presented rules for solving equations.
Today, algebra is the study of the properties of operations on numbers. Algebra generalizes arithmetic by using symbols,
usually letters, to represent numbers or unknown quantities. Algebra is a problem-solving tool; like a tractor or combine
is a farmer's tool, algebra is the mathematician's tool for solving problems. Algebra has applications to every human endeavor.
From art to medicine to zoology, algebra can be a tool. People who say that they will never use algebra are people
who do not know algebra. Learning algebra is a bit like learning to read and write. If you truly learn algebra, you
will use it. Knowledge of algebra can give you more power to solve problems and accomplish what you want in life.

Meet the Challenge!
To calculate a person's target heart rate for exercise (in beats per minute), exercise physiologists evaluate the expression
0.6( 220 - a ), where a represents the person's age in years. Calculate the target heart for Brianna, who is 25 years old,
and for her mother, who is 50 years old.
