-2 as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to learn about integers and decimals. An integer is a whole number that can be positive, negative, or zero. Decimals are a way to represent numbers that are not whole, using a decimal point to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
