When multiplying powers with the same base, the base stays the same and you add the exponents.

A common multiple of two or more integers is a number that all of them can divide into. The smallest one of these, excluding zero, is called the least common multiple of these integers.

Exponential growth refers to the phenomenon where a quantity keeps increasing at a fixed rate over a set period of time.

Coordinate geometry is basically the analytic geometry everyone knows, mainly relying on setting up a coordinate system and turning geometric shapes into algebraic equations to calculate.

In physics: it refers to how much matter an object contains, and is also a measure of its inertia. The unit is kilogram (kg) and it doesn’t change with location.

Coordinate axes are a set of reference lines used to determine the position of points in space. The most common ones are the horizontal axis (x-axis) and vertical axis (y-axis) in a plane Cartesian coordinate system, and they are perpendicular to each other and intersect at the origin.

A prime number is a natural number that has only two factors: 1 and itself. Numbers like this are called prime numbers, also known as primes.

Prime factors are the prime numbers that can exactly divide a given positive integer. In other words, if a prime number is a divisor of a number, then it is a prime factor of that number. This concept is also often called prime divisor or prime factor in math and is usually used to break down a composite number into a multiplication of prime numbers.

The point that divides a line segment into two equal parts is called the midpoint of the line segment.

The percentage increase or decrease is just the change in amount divided by the original base, then converted into a percentage.
