What is 5? (The sum of the exponents 3+2.)
This is the distance between a number and zero on the number line, always positive.
What is absolute value?
This is the key difference between an expression and an equation.
What is an equation has an equal sign, while an expression does not?
In the expression 3+4×2, this operation is performed first.
What is multiplication?
What is this polynomial expression called?
5y - 3z + 1
Trinomial
A term can be identified in an algebraic expression by looking at these signs that separate it from others.
What are addition and subtraction signs?
This acronym helps you remember the order of operations in algebra.
What is PEMDAS? (Parentheses, Exponents, Multiply/Divide, Add/Subtract)
This type of expression has only numbers and operations, like 7+3.
What is an arithmetic expression?
In the expression (2+3)2, this operation is performed after the parentheses.
What is squaring (or raising to the power of 2)?
What is this polynomial expression called?
10z
monomial
This is the name for a term that has no variable, like 5 in the expression 3x+5.
What is a constant term?
This is a letter or symbol used to represent an unknown value in algebra.
What is a variable?
This type of equation involves variables raised to the power of two, like x2+3x−4=0.
What is a quadratic equation?
If division and multiplication both appear in an expression, you solve them in this order.
What is left to right?
The highest exponent in a polynomial determines this important characteristic of the polynomial.
What is the degree of the polynomial?
In the term 7x3, this part determines how many times the base is multiplied by itself.
What is the exponent?
This is the term for a number written in the form a×10n, often used for very large or small values.
What is scientific notation?
When simplifying expressions, these operations are performed before adding or subtracting.
What are multiplication and division? (and maybe a couple of others...)
The result of the expression 23×(4+6) is this.
What is 80?
This type of polynomial has only one term, like 7x5 or 42.
What is a monomial.
A term in algebra is made up of these three possible parts.
What are a coefficient, a variable, and an exponent?
The number in front of a variable, such as the 3 in 3x, is called this.
What is a coefficient?
In a polynomial expression, the terms are usually arranged in this order, starting with the term with the highest degree. (a________ or d_________)
What is descending order?
When a fraction bar is present, it acts as a grouping symbol and indicates that these parts of the expression should be simplified first.
What are the numerator and denominator?
