Content Specific Language:

Base- The base is the big number in a variable expression with an exponent.

Distributive Property- The distributive property of multiplication is the property that states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products. a(b + c) = (a x b) + (a x c)

Equation- An equation is a number sentence that compares two quantities that are the same. It has an equals sign in it and may be written as a question requiring a solution.

Evaluate- To evaluate means to “find the value of”. We find the value of an expression.

Expanded Form- Writing a number in expanded form is when you remove the exponent from a base and write out the expression using repeated multiplication.

Exponent- An exponent is a number that shows how many times the base is used as a factor.

Exponential Notation- Exponential notation is writing multiplication using a base and an exponent.

Expression- An expression is a mathematical phrase, which contains numbers, variables, and operations.

Expression- An expression is a number sentence with operations and no equals sign.

Grouping Symbols- Grouping symbols are parentheses or brackets. Operations in parentheses are completed first according to the order of operations.

Like Terms- Like terms are terms with the same variable(s), raised to the same power(s).

Numerical Expression- A numerical expression contains only numbers and one or more operational symbols.

Operation- Operations refer to addition, multiplication, subtraction, or division. They can also be much more complex like an exponent or square root.

Order of Operations- The order of operations is the order that you perform operations when there is more than one in an expression or equation.

P - parentheses

E - exponents

MD - multiplication/division in order from left to right

AS - addition and subtraction in order from left to right

Parentheses- Parentheses are used as grouping symbols. They indicate which operations should be done first.

Power- A power is any expression in the form  The power is also used to refer to the exponent.

Simplify- To simplify means to make smaller or simpler with as few terms as possible.

Term- A term is a number, a variable, or the product of a number and a variable.

Variable Expression- A variable expression has variables, numbers, operations and sometimes exponents in it.

Variable- A variable is a symbol, usually an English letter, written to replace an unknown or changing quantity.
