In this second lesson, we will continue to study the definitions necessary for the study of Algebra and complete the second hour of instruction.

- Study the lesson Instruction below.
- Study the lesson content for mastery.
- Complete the lesson assessment.

## Instruction

## Lesson

In this second hour, we will review the study of the definitions of terms from hour 1 and discuss the content of articles 12-15 in Ray’s Primary Elements of Algebra.

- There are two kinds of questions in Algebra, Theorems and Problems.
- In a
**Theorem**, it is required to demonstrate some relation or property of numbers, or abstract quantities. - In a
**Problem**, it is required to find the value of some unknown quantity, by means of certain given relations existing between it and others, which are known. **Algebra**is a general method of solving problems and demonstrating theorems, by means of figures, letters, and signs. The letters and signs are called symbols.
