Across
- 3. To find the answer. In algebra, it means to figure out what the variable stands for.
- 6. Two lines in the same plane that never meet. Also, lines with equal slopes.
- 8. The shape made by two rays extending from a common endpoint, the vertex.
- 11. A small number written slightly above and to the right of a variable or number. It’s used to show repeated multiplication.
- 12. A grouping of terms or values that use a sign to show an equal relationship — that two quantities are equal.
- 13. Forming a right angle.
- 14. A grouping together of one or more factors (variables and/or numbers), such as 4xy.
- 16. A letter that always represents an unknown number, or what you’re solving for in an algebra problem.
- 17. To combine all that can be combined, reduce the number of terms, and put an expression in an easily understandable form.
- 19. An action performed upon one or two numbers to produce a resulting number. For example: addition, subtraction, multiplication, division.
Down
- 1. The length of the boundary around a figure.
- 2. Is a number used to multiply a variable like the 4 in “4x”
- 4. A value or number that never changes in an equation — it’s constantly the same.
- 5. The incline of a line, also known as “rise over run”
- 7. An angle with a measure of less than 90 degrees.
- 9. Any combination of values and operations that can be used to show how things belong together and compare to one another.
- 10. Any of the four regions formed by the axes in a rectangular coordinate system.
- 15. Terms that are "like" each other.
- 18. To change two or more terms to just one term so that you can perform other processes.
