I'm the loyal companion always standing right in front of a letter. I tell the variable exactly how many times it needs to multiply. What am I?
A number that multiplies a variable. It is the numerical part of a term that contains a variable, usually placed right in front of the letter.

I am a single chunk of a math sentence, separated from my neighbors by pluses and minuses. I can be just a number, just a letter, or a mix of both. What am I?
A single mathematical expression that makes up part of a larger equation or expression. A term can be a single number (a constant), a single variable, or numbers and variables multiplied together. Terms are separated by addition or subtraction signs.
Term
200
Variables come and go and change their minds, but I stay exactly the same. I'm a number on my own, and changing isn't my game. What am I?
A fixed value or a number on its own that does not change because it has no variable attached to it.
Constant
200
I'm the one doing the heavy lifting, standing on the ground, while my tiny friend up high tells me how many times to stick around. What am I?
In expressions with exponents, the ________ is the number or variable that is being multiplied by itself.
Base
300
We might have different numbers in front, but our letters and powers are identical twins. That's why you are allowed to add us together. What are we?
Terms in an algebraic expression that have the exact same variables raised to the exact same exponents. Because they are alike, they can be combined through addition or subtraction.
Like Terms
300
If you take a step forward, I pull you a step back. We are pairs of actions that always undo what the other one did. What are we?
Mathematical operations that reverse or "undo" the effect of each other.
Inverse Operations (Reciprocal)
400
I'm a math phrase entirely made of digits and symbols like plus or minus. You won't find a single sneaky letter hiding anywhere in my space. What am I?
A mathematical phrase that contains only numbers and operational symbols. It does not contain any variables.
Numerical Expression
400
I'm tiny and I sit up high. I'm the bossy one who gives the base instructions on how many times to multiply. What am I?
A small number written above and to the right of a base number. It tells you how many times to use the base as a factor in multiplication.
Exponent
500
I have numbers, operations, and letters too, but I never give you a final answer because an equal sign just won't do. What am I?
A mathematical phrase that can contain numbers, variables, and operation symbols (like addition or multiplication), but does not include an equals sign.
Algebraic Expression
500
I'm always positive (or zero), no matter how negative I start out. I just measure the distance back home to zero. What am I?
The distance of a number from zero on a number line. Because distance cannot be negative, the __________ is always positive or zero. It is written using two vertical lines.
Absolute Value
600
I'm a mathematical undercover agent in disguise. My true numerical identity is a secret until you solve the problem to figure out who I am. What am I?
A symbol, usually a letter, used to represent an unknown or changeable number in mathematical expressions and equations.
Variable
600
I'm the superhero combination of a big number on the bottom and a tiny one above. I represent the magic of repeated multiplication. What am I?
Often used interchangeably with "exponent," this refers to the entire expression of a base raised to an exponent. It represents repeated multiplication.
