Across
- 3. the property that states that numbers can be added or multiplied in any order and achieve the same result
- 4. to distribute or combine all like terms in order to reduce the complexity of an expression
- 5. An equation that is unsolvable, because the variables cancel each other and no value will make it balanced. Ex: 4x+5=4x+8; 5=8
- 8. An equation with multiple variables.
- 10. the answer to a subtraction problem.
- 12. a number that is being added or subtracted in an expression or equation; will always stand alone
- 13. a letter in an equation or inequality that represents an unknown number
- 14. All real numbers are solutions because both sides of the equation are the same and any value will make it balanced. Ex: 2x+5=2x+5
- 15. the answer to a multiplication problem.
- 18. a grouping of numbers, variables, and operations without an equal sign; can be evaluated and simplified
Down
- 1. a grouping of numbers, variables, and operations with an equal sign; can be solved
- 2. the answer to a division problem.
- 6. A pair of numbers that equal zero when combined. Ex: 3 & -3; 9 & -9
- 7. using opposite operations to cancel out coefficients and constants in equations and inequalities to isolate the variable; Ex: addition & subtraction
- 9. the property that allows you to multiply a number outside a set of parentheses with each number or term within the parentheses
- 11. a number multiplied by a variable; is always in front of a variable
- 16. parts of an expression or equation, which are separated by addition and subtraction that have the same variable and exponent
- 17. There is only one solution to the equation that will make it balanced. Ex: x = 4
- 19. the answer to an addition problem.
- 20. positive and negative whole numbers, as well as zero. Ex: -2, -1, 0, 1, 2
