What is Algebra?
Algebra is the part of mathematics that is used to help to solve problems. It provides a way for a problem and its solution to be written down.
In algebra, letters or symbols are used to represent numbers.
The letters are often called variables or pronumerals. In a problem the variable often stands for the unknown thing we are trying to find.
e.g. A problem might ask "What is the cost of 7 apples if each apple costs 50 cents?"
In this problem we could let c stand for the cost. So c would equal 7 x 50
This means we could write an equation: c = 7 x 50
Solving this equation would give c = 350 cents = $3.50
Most people would work out this problem in their head but algebra like this allows us to work out much more difficult problems.
