My 6+ Unit 6 VocabularyBy: Claire S.
Constant Term
A term that doesn’t change.
8, 88, 888, 8888, 88888, …
3,33,333,3333,33333….
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
Equation
A number sentence with an equal sign.
13+2 = 15
167+1 = 168
Equivalent equations
Problems that have the same solution to another problem.
6+6 = 12; 6x2 = 12
5+15 = 20; 5x4 = 20
Inequality
A number sentence with a relation symbol in it that is not equal.
15 = 14.6
13< 14
/
Integers
A whole number and/or the opposite of that number.
12 = -12
124 = -124
Multiplication property of -1
Anything multiplied by -1 will become it’s OPP.
-1x 234= -234
8907x -1 = -8907
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
Open sentence
A number sentence that has more than 1 variable.
a+b+4= n
c+s+3=k
Opposite of a number
When you change a number from positive to negative, or negative to positive. Also known as OPP.
-1 = 1
13579 = -13579
Order of operations
This tells you what order to go in when solving a number sentence.

Parentheses, Exponents, Multiplication, Division, Addition, & Subtraction
Reciprocal
A number when you add it, it always is 1.
5/3 + 3/5
1569/1 + 1/1569
Relation symbol
A symbol that shows relationship.
7=3+4
5<6

Solution
A solution to a problem is the answer.
1x 156= 156
2x78= 156
Solution set
A set of all solutions.
J = 16 ( J=4)
G = 49 (G=7)

Terminating decimals
A decimal that ends, unlike Pi.
0.7
0.564382
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)
Variable
A letter in a number sentence that could be any number.
12+e=17
12+f=15
