Across
- 3. A grouping of terms or values that use a sign to show an equal relationship — that two quantities are equal. By using an equation, tough problems can be reduced to easier problems and simpler answers.
- 5. A grouping together of one or more factors
- 7. the distance between a number and zero
- 11. To change two or more terms to just one term so that you can perform other processes.
- 12. is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.
- 13. To find the answer. In algebra, it means to figure out what the variable stands for.
- 14. is a fraction that contains an algebraic expression in its numerator and/or denominator.
Down
- 1. is an equation of the form:ax2 + bx + c = 0, where a, b and c are numbers and a ≠ 0
- 2. A value or number that never changes in an equation — it’s constantly the same.
- 4. Any combination of values and operations that can be used to show how things belong together and compare to one another.
- 6. It is the number that is placed in front of a variable.
- 8. A letter that always represents an unknown number, or what you are solving for in an algebra problem.
- 9. An action performed upon one or two numbers to produce a resulting number. Operations are addition, subtraction, multiplication, division, square root, and so on.
- 10. A small number written slightly above and to the right of a variable or number. It’s used to show repeated multiplication. An exponent is also called the power of the value.
- 13. To combine all that can be combined, reduce the number of terms, and put an expression in an easily understandable form.
