Unit 1: Number Sense
A number's distance from zero.
Absolute Value
A letter or symbol used to represent a number.
Variable
A mathematical sentence consisting of 2 expressions with an equal sign in the middle.
Equation
We do THIS to determine if 2 ratios are proportional.
Cross-Multiply
I have 4 congruent sides and 4 right angles.
Square
This is used to write really big or really small numbers, usually used in science.
Scientific Notation
This refers to the number that is with the variable.
Coefficient
This is a mathematical sentence stating that 2 expressions are not equal, but that one is greater than the other.
Inequality
This is where a function crosses over the y-axis.
Y-Intercept
I am a Quadrilateral with 4 congruent angles but not necessarily with 4 congruent sides
To convert a decimal to THIS, simply move the decimal 2 places to the right.
Percent
This refers to the number that does not contain a variable.
Constant
To solve an equation or inequality, you must perform these to undo current operations, for ex. for addition use subtraction, for multiplication use division.
Inverse Operations
This refers to how steep a line is in the coordinate plane. Also referred to as the "rate of change."
Slope
This is the name for the non-parallel sides of Trapezoids
Legs
In scientific notation, a number must be between one and ten and multiplied by this.
A Power of Ten
This refers to the amount of space inside a 3D figure.
Volume
This is the answer to a multiplication problem.
Product
This is what we call 2 plane figures who are the same shape, but different sizes.
Similar Figures
The 4 of THESE are Reflection, Translation, Rotation, and Dilation.
Transformations
This is the product of a number multiplied by itself.
Perfect Square
The mathematical term for the shape of a tissue box.
Rectangular Prism
In an inequality, these are what we call all of the possible "answers."
Solution (Solution Set)
In order for 2 figures to be similar, THESE must be in proportion.
Corresponding Sides
I am a quadrilateral with one pair of parallel sides, and my non-parallel sides are congruent.
Isosceles Trapezoid
