2. Constant term Some ting that stay the same like A+0=A no mater what a is it will be a added to 0 Examples Bx0=0 U-0=U

3. Division of fractions property When you dived fraction you flip the second fraction and multiply it Examples 2/4 dived by ¾ it would be 2/4 * 4/3 7/8 dived by 5/8 would be 7/8 * 8/5

4. Equation An equation is when you use a letter to replace a number Examples W+9=12 W=3 S-7=20 S=27

5. Equivalent equations A Equivalent equations is seeing if two equations are equal Examples 1+3+a=a+3+1 2x4+b=4x2+b

6. Inequality Inequality – not being equal 2+2≠5 90/3≠21

7. Integers A number that is not a decimal or a fraction such as … 7 12 21

8. Multiplication property of -1 Any positive number X -1 is that number – Any negative number X -1 is positive number 10 X (-1)=-10 -10 X (-1)=10

9. Nested parentheses Nested parentheses are parentheses are parentheses in parentheses (2+2)X8)+4= (3+3)X6)x3

10. Open sentence Open sentence is a sentence that says something about math matrices 5+5=10 The opposite of 3 is -3

11. Opposite of a number A opposite of a positive number is a negative number and other way a round The opposite of 3 is -3 The opposite of -17 is 17

12. Order of operations PEMDAS (please excuse my dear aunt sally) Order in which you solve an equation. 1)Parentheses 2)Exponents 3)Multiplication and Division 4)Addition and Subtraction

13. Reciprocal A reciprocal is a flipped fraction and a reciprocal times its fraction is always one ½ 2/1 9/7 7/9 ¾ X 4/3=1

14. Relation symbol Symbols that show how numbers compare to each other. 3>2 2x10=19+1

15. Repeating decimals A Repeating decimals are decimals that go on for ever 1/3=0.33333… Pie 3.14…

16. Solution An answer to a problem 4+4=8 9X9=21

17. Solution set The set containg all the solution 2+2 the set would have 4 in it 8X3 the set would have 24

18. Terminating decimals A decimal number that has digits that don’t go on forever. 0.23 0.75 Rather then.66666…

19. Trial and error method To find a solution, try one method. If it fails, try different methods until you find the answer. Example: show your work.

20. Variable A letter that takes the place of a number. 3+x=4 X=1 5x=15 X=3
