What is Volume?

Back

Volume is the amount of space a 3-dimensional object occupies, measured in cubic units (e.g., cubic centimeters, cubic meters). For example, the volume of a cube is calculated as the length of one side cubed.

What is a Variable?

Back

A variable is a symbol, usually a letter, that represents an unknown or changeable value in an equation or expression. For example, in x + 5 = 10, x is the variable.

Front

What is Sum?

Back

The sum is the result of adding two or more numbers together. For instance, the sum of 3 and 5 is 8.

Front

What is a Triangle?

Back

A triangle is a 2-dimensional shape with three sides and three angles. The sum of the interior angles of a triangle is always 180 degrees.

Front

What is a Trapezoid?

Back

A trapezoid is a 4-sided shape (quadrilateral) with at least one pair of parallel sides. The parallel sides are called the 'bases,' and the non-parallel sides are called the 'legs.'

Front

What does Times/Multiply By mean?

Back

'Times' or 'multiply by' refers to the operation of multiplication, where you combine groups of numbers. For example, 3 x 4 (or 3 multiplied by 4) equals 12.

Front

What is Symmetry?

Back

Symmetry is when a shape or figure can be divided into two or more identical parts that are mirror images of each other. Common types include line symmetry and rotational symmetry.

What is a Sign in math?

Back

In math, a 'sign' refers to whether a number is positive (+) or negative (-). It can also refer to mathematical symbols like addition (+), subtraction (-), multiplication (×), and division (÷).

Front

What is Value?

Back

Value is the actual quantity represented by a number, variable, or expression. For example, in x = 3, the value of x is 3.

Front

What is Surface Area?

Back

Surface area is the total area covering the surface of a 3-dimensional object. For example, the surface area of a cube is calculated by finding the area of one face and multiplying it by six.
