3. Division of fractions property
This is that if you divide a number, it would be the same as multiplying the same number by it’s reciprocal.
12/2 = 12 x ½
14/2 = 14 x ½

4. Equation
A number sentence with an equal sign.
13+2 = 15
167+1 = 168

5. Equivalent equations
Problems that have the same solution to another problem.
6+6 = 12; 6x2 = 12
5+15 = 20; 5x4 = 20

6. Inequality
A number sentence with a relation symbol in it that is not equal.
15 = 14.6
13< 14 /

7. Integers A whole number and/or the opposite of that number. 12 = -12
124 = -124

8. Multiplication property of -1
Anything multiplied by -1 will become it’s OPP.
-1x 234= -234
8907x -1 = -8907

9. Nested parentheses
A number sentence with a set of parentheses inside of another set of parentheses.
(13+(14-2)x 6) = d
(8-(13+4)+24) = e

10. Open sentence A number sentence that has more than 1 variable.

16. Solution
A solution to a problem is the answer.
1x 156= 156
2x78= 156

17. Solution set
A set of all solutions.
J = 16 ( J=4)
G = 49 (G=7) 1 1

18. Terminating decimals
A decimal that ends, unlike Pi.
0.7

19. Trial and error method
When you try different ways to solve a problem, and you do this until you get it right, this is trial & error.
n+e = 14 ( I would have to find what n and e would be)
e+r = 19 ( I would have to find out what e and r would be)

20. Variable A letter in a number sentence that could be any number.
