### Featured Multiplying and Dividing Decimals Vocabulary Words On These Puzzles

**Decimal** – A decimal is a number expressed in the base-10 numerical system, consisting of a whole number part and a fractional part separated by a decimal point. It allows for the representation of fractions and real numbers with greater precision than whole numbers alone.

**Dividend** – In division, the dividend is the number being divided by another number. It represents the total quantity or value that is being divided into equal parts.

**Division** – Division is a mathematical operation that separates a quantity into equal parts or groups. It is represented by the division sign (÷) and is the inverse operation of multiplication.

**Divisor** – In division, the divisor is the number by which another number is divided. It represents the number of parts into which the dividend is being divided.

**Estimate** – Estimating is the process of making an approximate calculation of a quantity or value, often to quickly assess the reasonableness of an answer. It involves rounding numbers and simplifying calculations to obtain a rough but close approximation.

**Exponent** – An exponent is a numerical value that represents the power to which a base number is raised. It indicates how many times the base number is multiplied by itself.

**Factor** – A factor is a number that divides another number without leaving a remainder. In multiplication, factors are multiplied together to find the product.

**Fraction** – A fraction is a numerical quantity representing a part of a whole, expressed as one integer divided by another integer, or as a decimal or percentage. Fractions are used in mathematical operations, including multiplication and division, to represent proportional relationships.

**Integer** – An integer is a whole number that can be positive, negative, or zero, without any fractional or decimal parts. Integers are used in arithmetic operations, including multiplication and division, and represent counts or quantities.

**Inverse Operations** – Inverse operations are mathematical operations that undo or reverse each other. For multiplication and division, multiplication is the inverse operation of division, and division is the inverse operation of multiplication.

**Multiplication** – Multiplication is a mathematical operation that combines two or more numbers to find their total or product. It is represented by the multiplication sign (×) and is repeated addition.

**Multiplier** – In multiplication, the multiplier is the number that is multiplied by another number to find the product. It represents the number of groups or the number of times the multiplicand is added to itself.

**Multiplicand** – In multiplication, the multiplicand is the number that is multiplied by another number to find the product. It represents the number of groups or the quantity being multiplied.

**Percentage** – A percentage is a fraction of 100, representing a proportion or rate per 100. It is commonly used to express ratios, proportions, or changes relative to a whole, making it a fundamental concept in mathematics and everyday life.

**Place Value** – Place value is the value assigned to a digit based on its position within a number relative to the decimal point. Each digit’s place value is determined by its position, such as units, tens, hundreds, and so on.

**Power** – In mathematics, a power is a product obtained by multiplying a number by itself a certain number of times. It consists of a base number raised to an exponent, indicating the number of times the base is multiplied by itself.

**Product** – The product is the result of multiplying two or more numbers together in a multiplication operation. It represents the total or combined value obtained by the multiplication process.

**Quotient** – In division, the quotient is the result obtained by dividing one number (the dividend) by another number (the divisor). It represents the number of equal parts or groups into which the dividend is divided.

**Rounding** – Rounding is the process of approximating a number to a specified place value or decimal position. It involves adjusting the value of the least significant digit based on the value of the next digit.

**Scientific Notation** – Scientific notation is a method of expressing numbers as a product of a decimal number and a power of 10, allowing for the representation of very large or very small numbers in a concise format.

**Square** – In mathematics, a square is a number multiplied by itself, resulting in a perfect square. It represents the area of a square with sides of equal length.

**Square Root** – The square root of a number is a value that, when multiplied by itself, gives the original number. It is denoted by the radical symbol (√) and is used to find the side length of a square with a given area.

**Variable** – A variable is a symbol or letter used to represent an unknown quantity or value in mathematical expressions or equations. It can take on different values and is used in multiplication and division to denote quantities that vary.

**Whole Number** – A whole number is a non-negative integer, including zero, that does not have any fractional or decimal parts. Whole numbers are used in arithmetic operations and represent counts or quantities.

**Zero** – Zero is the integer that represents the absence of quantity or value. It serves as the neutral element in multiplication and division operations, where multiplying or dividing by zero yields zero as the result.
