## Advanced Arithmetic

When numbers get larger than a single numeral, we must use place value and 'long' arithmetic. In this mini-curriculum, you will learn about place value, long addition, long subtraction, long multiplication and long division.

## Factors

The factors of a number are those numbers that multiply to make that number. They divide exactly into the number. In this mini-curriculum, you will learn about factors.

## Multiples

Multiples are the result of multiplying a number by another whole number. In this mini-curriculum, you will learn about multiples.

## Powers

Powers are the result of multiplying a number by itself. In this mini-curriculum, you will learn about the parts of powers.

## Laws of Exponents

The laws of exponents lets you do arithmetic with powers. In this mini-curriculum, you will learn about the laws of exponents.

## Reciprocals

Reciprocals of a number are 1 divided by the number. They can be denoted by an exponent of −1. In this mini-curriculum, you will learn about reciprocals.
