Unit 1 Math Vocaublary

Identity Property of Addition (Additive Identity Property of 0): The sum of any number and 0 is that number. Example 13 + 0 = 13

Algorithm: a process or set of rules to be followed in calculations or other problem-solving operations.

Area Model: a model for mulitpication problems, in which the length and width of a rectangle represents the factors.

Array: a rectangular arrangement of objects or elements organzied into rows and columns.

Associative Property of Addition: if the grouping of addends changes, the sum stays the same. Example 5 + (8 +14) = (5 + 8) + 14

Associative Property of Multiplication: if the grouping of factors changes, the product stays the same. Example 11 X (3 X 6) = (11 X 3) X 6

Base of an Exponent: is the number that is used as the repeated factor.

Braces: organize an algebra problem. Example {}

Brackets: are symbols used in pairs to group things together. Example ( ) , [ ]

Communtative Property of Addition:  if the order of addends changes, the sum stays the same. Exampel 12 + 7= 7 +12

Communtative Property of Multiplication: if the order of factors changes, the product stays the same. Example 4 X 9 = 9 X 4

Distributive Property: a rule or method that states that every term inside grouping symbols may be multipled by a term outside grouping symbols to yield an equivalent expression.

Dividend: the value to be divided in a division problem.

Divisor: the value by which another quantity is divided in a division problem.

Equation: a mathematical statement divided by an equal symbol that states the two values or expressions have the same value.

Estimate:  An approximate and resonable answer that is close to the exact answer without actually calculating the exact answer.

Evaluate: find the value of a numerical expression.

Exponent: is the number that tells how many times the base is used as a factor.

Expression: a mathematical phrase containing one or more terms linked by operation symbols.

Factor: the value that can be divided into another value with no remainder.

Inverse Operation: using the same numbers, multiplication and division are opposite.

Long Division: is a step-by-step process to divide large numbers into equal groups.

Identity Property of Multiplication (Multiplicative Identity Property of 1): the product of any number and 1 is that number. Example 4 X 1 = 4

Multiply: the operation of repeated addition.

Numerical Expression: is a mathematical phrase that has numbers and operation signs, but does not have an equal sign.

Order of Operations: tells you in what order you should evaluate an expression.

Parentheses: used around a fact or numbers within an equation "()."

Pattern: a set or sequence of figures or numbers that are repeated in a predictable manner.

Period: is a group of three digits separated by commas in a mulltidigit number.

Place Value: the value of a numeral based on the position of each digit in the number.

Powers of Ten: a power of 10 is the number 10 multiplied by itself by the number of times indicated by the exponent.

Product: the result obtained when two or more quantities are multiplied.

Quotient: the answer to a division problem.

Remainder: the number left over when an integer is divided by another.

Sum: the result of addition.

Whole Numbers: the set of numbers consisting of the natural numbers and zero.
