The two perpendicular number lines that intersect to form a coordinate grid. The numbering on both lines starts where they intersect at 0.
A grid, or pattern of evenly spaced intersecting lines, formed by the horizontal and vertical axes.
Example:
Example:
An ordered pair of numbers that tells an exact location on a coordinate grid. The first number represents a location on the horizontal axis. The second number represents a location on the vertical axis.
Example: The coordinates of point P are \((3, 4)\) because P is located 3 units from 0 on the horizontal axis and 4 units from 0 on the vertical axis.
The volume of a cube whose sides are each 1 unit long.
Example: A cube whose sides are each 1 inch long has a volume of 1 cubic inch.
Example: A cube whose sides are each 1 inch long has a volume of 1 cubic inch.
A number that tells how many times something is multiplied by itself.
Example: In \(10^3\), the number 3 is an exponent. It means to multiply 10 by itself 3 times.
\(10^3 = 10\times10\times10 = 1,000\)
The result of multiplying 10 by itself a given number of times.
Example: 1,000 is a power of 10 because \(10 \times10 \times 10 = 1,000\).
Example: 1,000 is a power of 10 because \(10 \times10 \times 10 = 1,000\).
A set of steps used to multiply numbers by place value. Write the numbers vertically, with the digits lined up by place value. Starting with the least place value, multiply the digits in each place of the bottom number by the digits in each place of the top number. Compose units in each place, as needed, representing that unit with a number over the place value to the left of the digit being multiplied. Add the partial products, including composed units.
