Mathematical statements are considered as?
Expressions and Equations
Explain uses for Principle 1.
Regrouping, assist to rationalize denominators, and reduce complex expressions for simplification
A*1=A
Principle 1
The product of any number and 1 stays the same.
A*1=A
A+0=A
Principle 2
The sum of any number and 0 stays the same.
A+0=A
_____ is never true or false.
Expression
_______ is like a mathematical phrase.
Expression
_______ is a mathematical sentence requiring an “=” symbol.
Equation
_______ cannot be solved but, rather simplified or evaluated.
Expression
_____ proves values on both sides of “=” sign are equal.
Equation
______ contains variables, numbers and mathematical operations.
Expression
Contains nonterminating, non repeating decimals.
Irrational Number
Cannot be expressed as a fraction with an integer numerator and a nonzero integer denominator.
Irrational Number
Terminating and repeating decimals can be expressed as fractions.
Rational Number
-6, -3.1, 0, 11/12, 9 4/5, 87, and 0.25=1/4 are examples of?
Rational Numbers
SQRT2, pie,-SQRT11/4, and 73.050050005… are examples of?
Irrational Numbers
5y+7, 12-x/5, and 8a(b-3) are examples of?
Expressions
3x+4=8, and t/9=12 are examples of?
Equations
2, 3, 5, 7, 11, 13, 17… are examples of?
Prime Numbers
4, 6, 8, 9, 10, 12… are examples of?
Composite Numbers
-4, -3, -2, -1, 0, 1, 2, 3, 4… are examples of?
Integers
If A=B then adding the same number to both sides makes the value equal.
Principle 3
If A=B then multiplying the same number to both sides makes the value equal, when C does not equal 0.
Principle 4
If a product of two numbers is zero, if and only life one them is zero.
Principle 5
A*B=0; either A=0 or B=0
Principle 5
If a product of two numbers is positive if and only if the two numbers have the same sign.
Principle 6
