Math

The base n raised to the power of a is equal to the multiplication of n, a times. An exponent refers to the number of times a number is multiplied by itself.

Many mathematical operations have an inverse, or opposite, operation. Subtraction is the reverse of addition, the division is the inverse of multiplication, and so on. Squaring, which we learned more about in a previous lesson, has an inverse too, called Square Root.

When you multiply a whole number (not a fraction) by itself, the outcome is a square number.

When you distribute something, you are dividing it into parts. In math, the distributive property helps simplify difficult problems due to the fact that it breaks down expressions into the sum or difference of 2 numbers.

When an element is multiplied by element of a particular set, it gives the element unchanged, is known as multiplicative identity.

Expanded notation can be defined as a way of expressing numbers by showing the value of each digit. Writing a number in expanded notation is not like writing in expanded form.

An element when added to a given element in a specified group provides that element unchanged is known as additive identity.

Logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if

Scientific notation is defined as a standardized way to represent any quantity as the product of a real number and a power of 10.
